Mr. Lause The date was March 31st, at 6:10 p.m. I obtain a phone call from Captain Muldoon of the local police department. An accident was reported by Mr. Miller about his wife, Mrs. Miller. The accident took place on 554 Theresa Drive. The incident occurred at 6:02 p.m. Mrs. Cleaver, the neighbor made minor remarks about Mrs. Miller’s background as there was no witness to the accident that led to Mrs. Miller’s death. According to Stephen Thompson, “Livor Mortis is when the body was moved.” (98) Which in this case Mrs. Miller’s body was moved from its original state, causing livor mortis. I, the world’s greatest detective, believe that Mr. Miller should be arrested for suspicion of second degree murder for numerous reasons. As Mr. Miller explained his story of what he had thought happened to his wife, Mrs. Miller. I noticed
Miller should be a suspect of second degree murder is because when we looked at the body we noticed Mrs. Miller had tiny scratches in the back of her calves which proved to be limestone. We can test the driveway to be sure that it is also made of limestone. When Mrs. Miller’s blood alcohol content was tested it came out negative, Mr. Miller told us she was drunk and that’s what caused her fall. We can test the saliva on the beer cans to make sure it wasn’t Mrs. Miller’s; we can also test Mr. Miller blood alcohol content. We should do a DNA analysis on the skin under Mrs. Miller’s nails; Mr. Miller has scratches on his chin and a glove one his right hand.
We also had medical evidence to help breakdown the case a little more. He bruises can prove foul play in Mrs. Miller’s death as well as the dislocation of her index finger and thumbs of her left and right hand. If Mrs. Miller had really fallen face forward which is common when people are drunk she wouldn’t have bruises on the back of her head. The fact that both her wrist are wrenched out of joint, leads us to believe she may have dragged by her
Inside Lopez’ right front pant pocket, Investigator Weber found Lopez’ CA issued identification card F4297435 and a single “Toyota” car key. Investigator Weber palpated Lopez’ head and found it to be extremely soft to the touch and was very unstable. When Weber moved Lopez’ body and head, I saw a full thickness laceration approximately 4 to 6 inches to the top of Lopez’ head. Lopez’ left face was extremely swollen and it had multiple lacerations. Inside the puddle of bright red blood I saw multiple white matter tissue which based on my training and experienced, I recognized as brain matter. I asked Weber what she suspected the cause of death to be and Weber stated it was most likely due to the severe blunt force trauma to the
On June 7th 2008, Sarah May Ward was arrested for the murder of Eli Westlake after she ran him over in a motor vehicle in St. Leonards. Prior to the incident the offender had been driving the wrong way down Christine Lane which was a one way street. Whilst this was occurring she was intoxicated, under the influence of marijuana, valium, and ecstasy and was unlicensed to drive. The victim and his brother who were also intoxicated, where walking down the lane and where nearly hit by the offender. This prompted the victim to throw cheese balls at the car and make a few sarcastic remarks regarding her driving ability. After a brief confrontation between the two parties the victim and his brother turned away and proceeded to walk down Lithgow Street. The offender followed the victim into the street and drove into him while he was crossing a driveway.
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.
That night, many witnesses reported having seen a man changing the tire of his van and waving any possible help away angrily while others reported seeing a woman wandering around the side of the dangerous highway. More witnesses reported that Kenneth and his wife were having many violent disputes at their home that usually resulted in Kenneth pursuing an angry Yvonne around the block. The most compelling evidence against Mathison, however, is purely scientific. Detective Paul Ferreira first noticed that the extensive blood stains inside the Mathison van. After hearing Mathison’s original account, he summoned the assistance of famed forensic expert Dr. Henry Lee to analyze what he thought was inconsistent evidence. Blood stains on the paneling and the spare tire in the cargo area reveal low-velocity blood stains meaning that the blood probably dripped from Yvonne’s head onto the floor. The stains found on the roof and steering wheel were contact transfer patterns probably caused by Mathison’s bloody hands. Blood stains on the driver’s side of the van were contact-dripping patterns which indicate that Mathison touched the inside of the van multiple times before and after moving his wife’s body. The final groups of blood stains on the instrument panel of the van were medium-velocity stains which show investigators that Mathison probably struck his wife at least once in the front seat causing the blood to fly from her open head wound. The enormous amounts of blood inside the van lead prosecutor Kurt Spohn to investigate the Mathison case as a murder instead of a misdemeanor traffic violation.
Tragically, the butchered upper-torso of Winter’s once-robust body was stumbled upon by his father, who had noticed the absence of his son since Sunday, March 11 (Smith 2002, 25-26). Unsurprisingly, an investigation occurred to obtain the identity and whereabouts of the murderer. When the various pieces of the body are found in differing areas of the town, theory begins to formulate that the murder was conducted by one of the two butchers in town; Adolph Lewy, a Jew, and Gustav Hoffman, a Christian, due to the precision of the cuts made upon Winter’s body (Smith 28).
Her body had been bathed and thoroughly washed before being placed, it was also completely drained of blood [2]. Two detectives were assigned to the case: Harry Hanson and Finis Brown. 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 in hopes of good evidence. 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.
To conclude, despite all the possibilities and other theories of Mrs. Maloney committing the crime out of anger or severe frustration towards Mr. Maloney, there is no credible way to prove it. Mrs. Maloney simply killed her husband as a result of mental anguish, self defense and trauma inflicted upon her. Mrs. Maloney did not plan to kill her husband. She was simply a victim of her situation and could not control her actions. Mrs. Maloney should not be spending time in jail, but safe at home grieving the loss of her husband.
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
In February of 1987, Miller was asked by police to help them, and even though he felt unwell due to his regular use of drugs and the assumption that someone else had slipped PCP into something that he had ingested, he agreed to help them. Miller rode to the police station and then was lead to an interview room by one of the detectives. Miller told the detectives that he had “powers” and that he could “see things through the killer’s eyes”. This prompted the detective performing the interrogation to make sure that the interrogation session was being recorded. After twelve hours of interrogatio...
...t I do not think that the evidence presented is enough for a conviction to sentence any man or woman to death.
This is clearly based on my experience with my mother that Ms. Pickett was not driving under the influence of alcohol and that her demeanor and irrational behavior had nothing to do with alcohol. Nevertheless, your testimony in this case is vital to prove Ms. Pickett’s innocence. With your testimony as an expert witness there is no doubt that the judge will find Ms. Pickett not guilty.

In the state of Florida, Homicide, the unlawful killing of a human being, includes several degrees of murder and manslaughter under the state laws. The type of homicide determines the prosecutor's requirements and the potential punishment in the case of a conviction. First degree murder, the most serious of the homicide charges available under Florida law, includes
When I arrived at the scene the first thing I noticed was the body. The coroner said he died from head trauma and was drunk. The wife says they fought before she went to a party. She invited some friends over afterwards. She was home for ten minutes before her friends arrived. She met them at the door and told them Mr. Volupides slipped and fell down the stairs when he was coming down for a drink. For a man who fell down the stairs he had unnaturally perfect clothes. After noticing his clothes I looked at the carpet on the stair and on the floor and how they looked untouched. After closer examination I realised he still had a glass in his hand. It also was unbroken. Nothing looked out of place on the wall on the stairs. His clothes were perfect,
Miller remembered the night of the murder after spending 2 weeks with the internal fairs department in the court room, and the testimony of 3 sworn witnesses, one of which was Ms. Miller who claimed that she saw Officer Woods and his partner pull over the Adams and Harris. She is the real reason that Adams was convicted because of her claim of saying that Adams was the man that had shot Officer Woods because she saw him in the driver's seat. Her and her husband make claims that they heard some sort of fire crackers but realized it was gun shots as they were from a distance. Morris uses more reenactments of the shooting and you can see as the camera rolls you see a driver in the driver seat but you can't really make out who it is besides that he has a mustache and the driver window rolling down but the screen goes black as soon as you hear gun shots. We later find out that Miller made claims that she was leaving the gas station where she worked early but was released that she was fired 2 weeks prior from the gas station. But the real reason they were speaking to the police was because there was a knife fight at her apartment and was booked for being drunk and disorderly. Morris shows a newspaper that offers a $21,000 reward for the conviction of the murder. Morris interviews a lady that made claims of talking to Millers husband saying that he hadn't seen a damn thing and that he was pondering the
