Case Analysis

1. The main challenges that the investigators faced while collecting evidence were contaminated crime scenes such as the ranch and also the place where Zavala and Camarera were held the walls were painted over and the residence cleaned. They also had a lot of trouble with the MFJP keeping them from conducting research and collecting evidence such as the license plate. The Mexican government also wouldn’t allow the FBI to do research a lot of the time, so it made it difficult to progress on the investigation.

2. The investigators found two cars that were involved with the abductions at the 881 Lope De Vega, the mercury grand marquis and the vw Atlantic. They also found a license plate belonging to one of the cars in a drain located outside the house. There were also forcibly removed hairs found in the guesthouse and bedroom number 4 along with rug fibers located on Zavala, which matched the fibers on the rug in the guest house.

3. The investigators found that the soil on the bodies did not match the soil of the area that they were found. Rafael- Quintero revealed that the bodies of two other Americans were buried in the south of LA Primavera Park in which the soil closely resembled the soil from the bodies SA Camarena and Captain Zavala. They found that the soil samples actually matched the soil found on Zavala and Camarena grain for grain.

1. Onlookers could destroy evidence at a crime scene by walking over the crime scene and destroying footprints, they could also move evidence such as weapons or other things left behind, interfering with the investigators. They could also damage fingerprints and other DNA left behind.

2. Some evidence that was left behind was blood spots found at the crime, markers for evidence found, a lamp or light source in the room, measurements from the body and of the room, didn’t indicate if it was carpet or hardwood, or tell if the body was lying face up or facedown.

3. Investigators could find physical evidence such as fingernails, blood, scratch marks, hair, ripped clothing etc to determine a struggle between the victim and perpetrator.

4. If the body was found in water, or left out in the heat or a cold caller, it would be difficult to test the processes rigor mortis, algor mortis, and liver mortis.
