Cosmo Dinardo has confessed to murdering the four young men who went missing in Pennsylvania last week.
The background of the 20-year-old Pennsylvania man reveals a strange and creepy history of behaviors, including previous arrests, numerous interactions with police and alarming observations from people who knew him.
Last Monday, July 10, Dinardo was arrested on an unrelated charge of illegally possessing a shotgun and ammunition stemming from a February offense.
According to court documents, Dinardo was prohibited from possessing a firearm due to a history of mental illness. He had previously involuntarily been committed to a mental institution.
On Tuesday, July 11, Dinardo’s father paid 10% of his $1 million bail – $100,000 in cash – and Dinardo was released.
The next day, Wednesday, July 12, Dinardo was arrested again. This time for stealing the car belonging to one of the victims and attempting to sell it for $500.
His bail for both felony charges was set at $5 million.
According to what a law enforcement source told ABC News, Dinardo “has had contact with police more than 30 times, although most of those cases have not resulted in arrests.”
It’s unclear to what caused those numerous interactions with police, however, his most recent involvement with law enforcement occurred in May this year. Dinardo was issued a citation for not having proper boater’s education paperwork.
A History Of Strange Behavior
Dinardo’s social media profiles reveal an eerie past of odd behavior.
A neighbor of the Dinardo family described him as “pretty nutty.” He told the Trentonian, “He used to walk around here in camouflage with a gun hunting squirrels. He’s a scary kid.”
Photos on Dinardo’s now-deleted Facebook page show that he was an avid hunter.
A friend of one of the victims – who hung out with Dinardo in the weeks prior to the murders – told The Philadelphia Inquirer that Dinardo had “spoken about weird things like killing people and having people killed.”
He added that “Something about him just struck me and all my friends, something about him – his behavior was a bit suspicious. He’s made a lot of scary insinuations in the weeks leading up to this.”
Along with his confession to the murders, Dinardo told police that after killing his victims, he had burned them at his family’s farm.
Authorities have identified the remains of 19-year-old Dean Finocchiaro. His body was discovered in a 12½ -foot-deep grave on the Solebury Township farm along with other human remains that have yet to be identified. Those victims include Tom Meo, 21, Mark Sturgis, 22, and Jimi Tar Patrick, 19.
The 68-acre farm is owned by Dinardo’s parents, Antonio and Sandra DiNardo; whom have been subpoenaed in relation to the crime.
Property records indicate that the Dinardo family has sizable real estate holdings. A report from NBC Philadelphia reveals that the Dinardo family “earned a fortune in real-estate and concrete and trucking business ventures.”
A look into the past of this confessed murderer points to some extremely disturbing facts.
