Improper Forensic Science - Gilbert Alejandro

Gilbert Alejandro



The Crime
In 1990 in Ulvade County, Texas a woman was pushed into her own apartment and aggressively
sexually assaulted. She was placed face down with a pillow over her head and threatened with
death if she screamed for help, she was raped. The victim described her attacker as a Hispanic
male that was about six feet tall and wearing a white cap (Gilbert Alejandro).


The Investigation  
Throughout the investigation the police questioned a man that was wearing similar clothes to
that description but no arrests were made. Through a DNA examination of sperm left on the
victim's clothing, Gilbert Alejandro was identified (Gilbert Alejandro). The victim failed to identify
Alejandro in several photo lineups, but made one identification in a sketch lineup which lead to
a positive identification in a live lineup.


The Trial
During the trial the most convincing evidence was the DNA test. Forensic Scientist Fred Zain
conducted the original DNA test and testified in court that the evidence conclusively matched
Alejandro (Gilbert Alejandro). With confirmation that he was absolutely positive about the
identification and that the DNA could not come from anyone else. Gilbert Alejandro was
sentenced to twelve years in prison.


The Exoneration
Four years later Alejandro convinced the courts to reexamine the DNA test. This time it came
back with completely different results. The fact surfaced that Fred Zain, the forensic scientist
who ran the results, had not even completed the test before testifying in court (Gilbert
Alejandro). The new results came back excluding Alejandro from the one whose DNA
evidence was found at the crime scene. Gilbert Alejandro’s conviction was overturned and he
was freed from prison. Fred Zain was fired after it was revealed that he had fabricated forensic
evidence from many murder and rape cases in West Virginia (Gilbert Alejandro).

Malcolm Bryant: Exonerated by DNA

Malcolm Bryant: Exonerated by DNA On the evening of November 20, 1998, 17-year-old Tyeisha Powell and 16-year-old Toni Bullock were confronted by a man carrying a knife. They were dragged into a vacant lot in Baltimore, Maryland and Bullock was stabbed to death. Powell managed to escape and later gave police a description of her attacker. She only saw him briefly and other factors such as poor visibility in the rain and evening made it hard for her to give an adequate description. A week later with no leads, police receive a phone call from members of the victim’s family saying a man resembling the sketch was just released from jail. Bryant was picked up and immediately put in a photo lineup where Powell identified him as the attacker. Bryant was charged with first-degree murder, even though witnesses placed him at a nightclub at the time of the crime. Bryant was sentenced to life in prison in 1999. Over the years, Bryant filed motions only to be dismissed and until 2009, ...

Voice Comparison Convicts The Crime In July of 1985 in Dallas County, Texas, a man knocked on a woman’s door asking if somebody lived there, and then immediately left. The following morning at 6 AM the woman awoke to find the man standing over her bed with a knife. He assaulted and raped her, and fled the scene. She called the police and reported the crime.

David Shawn Pope became a suspect after police saw him around the area and thought he looked similar to the sketch. Pope was presented to the victim multiple times in a photo lineup, along with other similar looking males and no identification was made. After there was no identification, those six peop...
