DNA Evidence Collected By M-Vac Helps Solve 40 Year Old Cold Case

Investigators Use Aggressive Wet-Vacuum DNA Collection Method On 1977 Murder

On December 4th, 1977 Sharon Schollmeyers was a 16 year old girl living in an apartment in downtown Salt Lake City, Utah. Unfortunately, there was a murderous stalker who was dangerously close and it proved to be deadly for her. According to court documents the next day Sharon was found by her mother naked in her bathtub in 6 inches of water with a gag in her mouth and a halter-top around her head as a blindfold. She had been strangled, suffocated and her death was ruled a homicide.

In the 1977 police report, the building manager, Patrick McCabe, let the victim’s mother into the apartment and waited in the living room as the mother searched for her daughter. When the victim was discovered McCabe made the 911 call to report the incident. Unfortunately, despite a thorough investigation, the case went cold. However, the investigators were astute enough to properly preserve the evidence which would, as new technology became available, provide the DNA profile that would ultimately lead to the arrest. Amazingly, the building manager that had made the original 911 call was the same man that had raped and murdered the victim.

“As a law enforcement agency, we never give up on a case,” stated Detective Wilking, the Salt Lake City PD PIO.  “We are always looking for that piece of the puzzle that will make the difference.  In the Sharon Schollmeyers case, the M-Vac came through for us and produced a full DNA profile that we didn’t have before, which led to the CODIS hit.  Sharon and her family have been waiting almost 40 years for justice, and thanks to the latest in technology, determination and the hard work of many investigators over decades of effort we were able to bring this case to a close and provide the justice that Sharon deserves.” 

According to the court documents, the case evidence was submitted to a private crime lab in Salt Lake City for M-Vac DNA testing, including the halter-top that was used to blindfold the victim. Despite almost 40 years after the heinous crime had been committed, the aggressive collection method produced a full DNA profile that could be loaded into the federal DNA database, and the match to Patrick McCabe was made. McCabe has since been convicted of 2nd degree murder and aggravated burglary and faces up to life in prison.

“We are extremely proud of the way the M-Vac performed in this case,” said Jared Bradley, President of M-Vac Systems. “Agencies that are using the M-Vac, especially for difficult cases or when the evidence is large, rough or porous like in the Shollmeyers case, are getting really impressive results. Salt Lake City PD is one of those agencies that has successfully used the M-Vac on a number of cases and we are excited to hear of these latest results. Most importantly though is Sharon can now rest in peace and her family can move on knowing Sharon’s killer has been caught.”

The M-Vac System is being utilized by an increasing number of police agencies and crime labs both in the United States and internationally. As investigators are assigned difficult cases, having a tool like the M-Vac immediately available helps immensely. It can collect critical DNA evidence from a variety of surfaces at the crime scene, in the evidence processing facility or in the crime lab. As the world’s most advanced wet-vacuum forensic DNA collection system, the M-Vac opens up cases and evidence to potential DNA profiles that were not available in the past.

Case No: 171902460 FS 3rd District Court, Salt Lake County, Utah
