DNA testing leads to exoneration of California man imprisoned nearly 3 decades on kidnapping and sexual assault convictions

In January 1995, a man and woman were robbed at gunpoint by two men who had also sexually assaulted the woman. Days after the crime, Gerardo Cabanillas, who was 18 at the time, was arrested because he generally matched the description of one of the suspects. Mr. Cabanillas was coerced by the investigating detective into giving a false confession after 7 hours of interrogation and promises of leniency. Mr. Cabanillas was sentenced to 87 years to life in prison for kidnapping, sexual assault, carjacking, and robbery. After 28 years in prison, DNA was shown not to match Mr. Cabanillas, and instead pointed to other perpetrators. The court used this information to dismiss the case and declare Mr. Cabanillas factually innocent.

Exoneration of Albert “Ian” Schweitzer

In 1991, Albert “Ian” Schweitzer was convicted for the sexual assault and murder of Dana Ireland. After 25 years of wrongful incarceration, on January 24, 2023, his conviction was dismissed based on new DNA testing that excluded him as a contributor to DNA evidence collected from the crime scene and instead identified one unknown male perpetrator. Mr. Schweitzer’s wrongful conviction was also impacted by false testimony, false confession, and ineffective assistance of counsel.

Cal State LA’s California Forensic Science Institute’s Postconviction funding supports DNA testing that leads to the exoneration of Maurice Hastings after serving 38 years in state prison

Maurice Hastings served more than 38 years in state prison for the 1983 murder of Roberta Wydermyer in California and two attempted murders, but new DNA evidence instead pointed to another man who died in prison in 2020. At the time of the victim’s autopsy, semen was detected in an oral swab. Mr. Hastings had maintained his innocence from the moment he was arrested, but a request for DNA testing of the swab in 2000 was denied by the Los Angeles County District Attorney. Eventually, Mr. Hastings was able to put in a claim of innocence to the Los Angeles County District Attorney’s Conviction Integrity Unit in 2021 and DNA testing found that the semen was not his. The DNA profile instead matched a man who had been convicted of an armed kidnapping where he placed his female victim in a trunk of a vehicle. On October 20, 2022, Mr. Hastings was released from prison and his 1988 conviction was vacated.

Forensic Genetic Genealogy Laboratory Considerations and Technology Limitations

The application of forensic genetic genealogy (FGG) has technological limitations and will not resolve every case. By taking the time to thoroughly evaluate cases and associated evidence with both local crime laboratory representatives and FGG vendor laboratory representatives, law enforcement investigators can greatly increase the chances of attaining successful case resolutions with FGG. This brief provides the SAKI TTA Team’s guidance on evidence submission based on current successes seen within the field and suggested questions to consider when choosing a FGG laboratory vendor [Description provided by the SAKI TTA website].

Exoneration of Terance Calhoun

In 2007, Terance Calhoun was convicted of sexual assault of two victims. DNA testing excluded him in 2007. Additional DNA testing was performed in 2019 by Bode confirming the original testing. On January 10, 2022, the Michigan State Police reported that a search of the FBI DNA database linked the DNA profile from the condom to a man who “is currently charged with other sexual assault offenses in the Detroit area that are alleged to have occurred between 2007 and 2014.” He was exonerated in April 2022.
