Experts confirmed that there was no way of knowing how long Samantha's blood had been on the comforter. Because she lived in the home and two weeks before her death she cut her lip and scrapped her knee. George Pitt's DNA did not match any of the samples collected from the crime scene. The only DNA found belonged to Samantha O'Toole. The hairs found on Samantha were never tested, and most likely the butts and condom hadn't been either. Which probably means the lighter wasn't tested for prints.
According to the Innocence Project (2006), “On September 17, 2001, Chad wrote the Innocence Project in New York, which, in 2003, enlisted pro bono counsel from Holland & Knight to file a motion for DNA testing on Tina’s fingernail scrapings.” The state had tested the DNA that was under Tina’s nail from the first case but at that time it was inadequate and could not be tested. It was not until now that we have the technology capable enough to test it. In June 2004, the test came back negative to matching both Jeremey and Chain Heins but did come from an unknown male. The state argued that it was not enough to overturn the conviction so Chad’s attorney asked the state to do some further testing and to compare the DNA from under the fingernails to the hairs that was found on Tina’s body. It was in 2005 that the Florida Department of Law Enforcement confirmed that there was a match between the DNA under Tina’s nail and the pubic hair. According to LaForgia (2006), “this particular type of DNA, the report stated, was found in only about 8 percent of Caucasian American men.” During this process there was a new piece of evidence that Chad’s attorney had learned about during the appeals process, a fingerprint. There were some accusations that the prosecutors never disclosed this information about this third fingerprint and if they did it was too late. The jurors did not even know about this fingerprint and if they did this could have changed the whole case. This fingerprint was found on several objects that included the smoke detector, a piece of glass, and the bathroom sink. It was soon discovered that this fingerprint matched with the DNA found on the bedsheets that Tina was on. This was finally enough evidence to help Chad Heins become exonerated in
The first piece of evidence that led to this theory was ice tray that was located at the crime scene. Due to the chromatography paper which was tested in Forensic Lab 7, it was revealed that the ice tray was poisoned by the one and only Beverly Hilis. In the Forensic Report it states, “The ph in the ice water was 9”(Forensic Report). This is significant, because this was the exact same ice tray Max used in his drink. The only person that was able to poison Max at the crime scene was Beverly. This is important, given the fact that the chromatography tests results showed that the ice tray was poisoned, Beverly could have made the poison because she is use to performing experimental things especially being a Chemist. Another piece of evidence that led to suspicion was Dez’s towel which was found at the crime scene. In the Preliminary Report it states,“ I took my dog down to the beach for a walk around noon”(Preliminary Report). If Dez was not near the beach house during the time of the murder then it raises the suspicion of why his towel was located at the crime scene. In addition to Dez’s towel being at the crime scene there was also the smell of cologne on the towel. In Forensic Lab 4, after testing out each of our suspects (Dez, Beverly, Chloe, and Ray) cologne we concluded that the cologne does match Dez. Due to the Forensic Report it stated, “The smell that
With Every Drop Of Blood by James Lincoln Collier and Christopher Collier is based on the Civil War. In this novel they talked about the white-black relationships during this time period. In the novel Johnny’s father went off to fight in the war, and was shot at Cedar Creek to be sent back home for a short amount of time before he passed due to his injuries. When Johnny’s father died Johnny promised him that he would not run off to fight, that he would stay and help his mother with the farm, the house, and Johnny’s little brother Sam and his little sister Sarah. Before Johnny’s father passed Johnny asked him what the reason for the war was, and his father told him it was for ‘states rights’.
The brand of the cigarette butt is legible, which, following identification of the victim or perpetrator, can be used as an identifying feature as evidence in court. The brand of the other cigarette butt is unknown, but could identify an individual who rolls their own. Further, DNA and finger prints could be traced on both.
We were presented with many facts that all pointed to Mr. Washburn as the murder. In the house all of the entrances were thoroughly inspected by authorities, and they found no sign of ransacking. “[They] examined all the locking mechanisms, all the doors and windows. In [their] opinion there was no evidence of any forced entry” (P.81). When police looked for fingerprints, “They were all of the Washburn family and the maid” (P.81). There was no trace of an outside party; somebody usually in the Washburn house committed the murder. While in the living room, an officer found a drop of blood. The evidence technician was called the next night to run some tests. “He sprayed the living room carpet with luminol. It is a luminous spray, and when it comes in contact with blood it illuminates” (P.82). To both men’s surprise the whole living room was illuminating. After spraying further the men found a trail from the living room through the kitchen to the garage. In the closet the men found a wet mop, which was tested for blood and also came back positive. Somebody tried to clean his or her bloody mess, and try to save himself. The physical evidence proves the killer was somebody who was familiar to the Washburn household.
The discovery of this crime began as a fishing trip for Chris Henkle, Dee Connors and his two children Sam and Claire on May 5, 2004. While relocating the boat to find better fishing, Connor spotted a suitcase floating in the water. As young Sam opened the suitcase hoping it contained pirate’s treasure, he found its contents to be wrapped in black plastic trash bags. Upon opening the trash bags, Sam exposed two human legs. Shocked at what they had found, Henkle immediately contacted the police. After Master Officer John Runge of Virginia Beach’s Marine Patrol Unit took possession of the suitcase from Henkle and Connors, he looked inside and called his superior asking for a homicide detective. Virginia Beach Homicide Detective Janine Hall joined by senior technician of the Forensics Unit, Steve Stockman, and Dr. Turner Gray, Virginia Beach Medical Examiner, arrived at the scene. The suitcase was photographed, then the body parts were taken back to Dr. Gray’s office for an autopsy. Detective Hall took the Kenneth Cole suitcase to the Virginia Beach police headquarters for forensic examination after the legs were removed for autopsy. Forensic unit supervisor Beth Dunton and Steve Stockman then tested the suitcase for trace evidence. To test for fingerprints, the bags were hung in a cyanoacrylate chamber in which fume...
I agree with some of Barbara Kingsolver’s statement, but not all of it. I agree when she says traditional families are for the most part are stable and show successful relationships to their children. However, I do not agree when she says the traditional Barbie and Ken households are never disassembled by divorce. I also do not agree when Kingsolver said the divorce people, gay families, Brady Bunch families, and single parent households result in failures for children.
Even though the prosecution presented evidence to the court, the only clear-cut hard fact the prosecution had against Anthony was that she failed to file a report for her missing daughter Caylee and that when she finally did a month after her daughter had gone missing, she proceeded to lie profusely to the authorities on the events that took place. The prosecution focused highly on the forensic evidence of decay located in the trunk of Casey Anthony’s car. The use of a cadaver dog to search the vehicle led investigators to be able to determine that a decomposing body had been stored in the trunk of the car. The forensics department used an air sampling procedure on the trunk of Casey Anthony’s car, also indicating that human decomposition and traces of chloroform were in-fact present. Multiple witnesses described what they considered to be an overwhelming odor that came from inside the trunk as it where the prosecution believes Caylee’s decomposing body was stowed. Several items of evidence were ruled out to be the source of the odor, as experts were able to rule out the garbage bag and two chlorine containers located in the trunk as the source. The prosecution alleged that Casey Anthony used chloroform to subdue her daughter and then used duct-tape to seal the nose and mouth of Caylee shut, inevitably causing her to suffocate. Based off the
Love is considered a wonderful connection between two people that brings happiness to many. Although without hate no one would realize how marvelous love truly is. Does this mean hate is more powerful than love throughout the world? Hate overpowers love because there may be so much love in this world, but with the tiniest bit of hate everything could be changed in a split second. Hate is an indestructible power that will demolish anything in its way, like it did in The Coffin Quilt, by Ann Rinaldi. Roseanna McCoy and Johnse Hatfield’s love was simply not powerful enough to defeat the hate that came along with the love.
Vecchiotti and Zoppis wrote that the bra clasp reportedly wasn’t examined until 46 days after the murder, allowing rust to build up with the sample. According to the Netflix documentary, the police at the crime scene did not handle the evidence correctly; their procedure wasn’t sterile because there were police reportedly working throughout the crime scene without protective suits and latex gloves were not changed as often as they should have been. The bra clasp was also reportedly examined immediately after investigators had already handled and examined numerous other items belonging to Kercher, which were most likely covered in her DNA. This could allow the defense to argue that one of the investigators on the scene accidently brought some of Sollecito’s DNA from somewhere else in the apartment and somehow transferred it to Kercher’s
During the investigation several fibers and two hairs were found on the boys, one negroid hair and one Caucasian hair.(Sauls) None of these hairs or fibers could be linked directly to any of the three boys. This evidence was also somewhat just tossed aside and overlooked for the remainder of the case… I wonder why?
Two detectives were assigned to the case: Harry Hanson and Finis Brown. [2] When they and the police arrived at the crime scene, it was already swarming with people, gawkers and reporters. The entire situation was out of hand and crowded, everyone trampling all over any hopes for good evidence. [2] One thing they did report finding was a nearby cement block with watery blood on it, tire tracks and a heel print on the ground. There was dew under the body so they knew it had been set there just after 2 a.m. when temperatures dropped to 38 degrees.
Capote opposes the death penalty, almost pleading that Perry is insane. As the Psychologist is unsure of whether or not Perry is insane, the court quickly shuts that escape route down. The imminent death of Perry and Dick makes the reader feel split on the two, where they would rather have Dick put to death and let Perry live, if the reader so chooses that Perry is insane.
When the first responder got to the scene he adimatately meet the 911 caller, who lead him to a car in an apartment parking lot. The car doors were closed and all of the windows were fogged. The police officer used his flashlight to see inside of the car before opening the door. He found a young African American woman who had been shot several times. The officers quickly called for backup, investigators and medical personnel. While awaiting for their arrival he secured the crime scene with caution tape, creating an initial perimeter setup as discussed in lecture two. Once everyone arrived he left it to them to search the car while he talked to the 911 caller, witnesses and others who had information on who had been present in the car. The investigators were able to collect physical evidence of bullets and cartage casings that were found outside the vehicle and inside the vehicle on the floorboard of the driver’s side. The team determined the bullets came from a 40 caliber. Other types of physical evidence that were found on the scene were the bloody clothing on the victim, the victim’s cell phone and fibers in the car from the driver’s side. personnel at the scene crime took several photographs, powered test for finger prints and did a blood spatter analysis. Stewart’s autopsy revealed that she had been shot at close range in the left hand once and in the
The container match but the fingerprint was different. That’s not realistic because normal. The hair and fingerprint match. This unbelievable and kind of impossible to happen. No one couldn’t have even predicted it. I think this is an inside job and could have something to do with Dr.Scapetta husband’s
