Authorities confirmed via genetic testing that human remains found in a trash bag inside a manhole at 82-year-old Sylvia Frens’s last residence were, in fact, hers. Frens was previously reported missing by concerned family members in 2018. An autopsy revealed that her cause of death was blunt force trauma and ruled her death a homicide.
Frens’s son, Richard Vandervelde, 54, was subsequently arrested on first-degree murder charges, as well as charges of tampering with a deceased human body, crimes against an at-risk adult, fraud-identity theft, theft, motor vehicle theft, and abuse of a corpse. He was in Florida at the time of his arrest.

Not even a week after Frens was reported missing, Vandervelde was pulled over for a traffic violation in Missouri while driving his mother’s car. Authorities took him into custody to question him more after he gave police a false name. Police then discovered he had been using his mother’s debit card and taken $10,000 out of her bank account, more than half of which was in the car at the time. Vandervelde said the transactions were all authorized by his mother.
A phone found with Vandervelde revealed Feb. 2018 searches for “map of desolate places in Colorado” and “least traveled areas near grand junction co.”
Records also found searches for “knocking someone out with a blow to the head,” “knocking someone unconscious,” “how to knock someone out without killing them,” “how to knock someone unconscious safely for a long time,” “5 ways to knock someone out in under 10 seconds,” “how to knock someone out quickly and quietly,” and an article about knockout drugs.
It wasn’t until March 2022 that police were able to get permission from the new occupants of Frens’s former residence, which she shared with her son.
Vandervelde is now at the Mesa County Detention Facility, awaiting arraignment on a $1 million cash-only bond. His next court date is Jun. 21.
