A cold case from 1985 in Claremont has been solved using forensic technology, the Los Angeles County Sheriff’s Department announced Wednesday.
On October 13, 1985, David R. Evans II was discovered brutally beaten to death inside his home at 862 High Point Ave. in Claremont.
Police were the first to find the 57-year-old man after a home robbery.
Evans, vice president of Pomona First Federal Bank and a former school principal, lived alone and no suspects were immediately identified. Evans’ 1980 Chevrolet Manza was stolen and two hours later was found abandoned in Covina.
Evans’ case went cold, until 2006.
The LA County Sheriff’s Department said advances in forensic technology, such as fingerprint technology, helped them identify a person of interest named Hillery Marcus Dupleasis, but that’s only in 2020 that he would be named a suspect.
In May 2022, the LA County District Attorney’s Office filed charges against Dupleasis in the murder.
Dupleasis is currently serving a prison sentence in New York for an unrelated murder and is awaiting extradition. He was to be eligible for parole in this case in 2033.
The sheriff’s department said resolving the case was a collaborative effort with Claremont Police, New York State Police and the New York Department of Corrections.
It remains unclear what the suspect’s motive was at the time of the murder. Investigators believe that prior to the murder, the two had never met.
