Cosmo DiNardo, who is being charged with the murders of four men killed in Bucks County, Pennsylvania, has admitted to authorities that he has killed before, according to CBS Philly.
The 20-year-old reportedly confessed involvement in at least two other killings in Philadelphia in the last five years.
Authorities are investigating DiNardo's claims.
The 20-year-old who was charged in the slayings of four people on his family farm outside of Philadelphia, Pennsylvania, provided police with grim details of the killings, saying he crushed one of them with a backhoe after shooting him and attempted to set three of the bodies on fire in a metal bin, with the help of his cousin, Sean Kratz.
DiNardo further explained to police that the killings were the result of a drug deal gone wrong. He disclosed to investigators that he had wanted to set the victims up when they visited the farm to purchase marijuana.
According to Bucks County District Attorney Matthew Weintraub, authorities may have never found the bodies if it weren't for DiNardo's cooperation.
"I don't know what convinced him (to confess). I'd like to think he wanted to get these boys home."
DiNardo has a record of mental illness that includes involuntary commitment, a schizophrenia diagnosis and repeated run-ins with police. Last year, he also suffered a head injury after an ATV accident.
By cooperating with police, DiNardo was charged with four homicide counts and 20 other crimes, including abuse of a corpse, conspiracy and robbery, but escaped the death penalty. His cousin Kratz faces 20 counts, including three homicide counts. They were both denied bail on Friday, and will be jailed separately after prosecutors determined that the men were dangers to society.
The man who confessed to killing four missing men at a family farm 30 miles outside of Philadelphia, Penn., reportedly felt "cheated" or "threatened" during three drug transactions, a source speaking on the condition of anonymity told The Associated Press.
"Every death was related to a purported drug transaction, and at the end of each one there's a killing," the person said.
The source added that a co-conspirator was also involved in the deaths.
Cosmo DiNardo, 20, has “confessed to his participation or commission” in the killings of four men missing in Bucks County, PA since last week, according to his defense attorney.
“In exchange for his confession, Mr. DiNardo was promised by the district attorney that he will spare his life by not invoking the death penalty,” Paul Lang said outside the Bucks County Courthouse Thursday, according to The Philadelphia Inquirer.
“We negotiated this outcome for Cosmo to be very honest, forthright and truthful in what occurred within the last week and half,” Land added, noting DiNardo also told the district attorney where to find the bodies of all four men.
“[DiNardo] did give a full confession and he was very forthright and gavel all relevant details that he could.”
Some Twitter users on Thursday voiced outrage over the news regarding DiNardo, who reportedly had an apparent connection with all four victims.

Cosmo DiNardo buried one of the bodies in a 12 1/2 foot deep grave.. The other 3 bodies are probably deeper than that. Unreal ..— Susan Hunt (@StSusanHunt) July 13, 2017
Death penalty is a joke..would have taken them 25+ yrs to kill Cosmo DiNardo on death row. He's just protecting his family and their assets— Kevin Killion (@ksquared007) July 13, 2017
Bucks County District Attorney Matthew D. Weintraub reportedly confirmed late Wednesday that investigators had found the remains of multiple bodies at a farm in Bucks County, PA.
Weintraub admitted that Dean R. Finocchiaro, 19, of Middletown, PA was among the dead after disappearing last Friday.
Tomas Meo, 21, of Plumstead, PA, Mark R. Sturgis, 22, of Pennsburg, PA and Jimi Taro Patrick, 19, of Newtown, PA all remain missing after vanishing last week.
DiNardo had reportedly been jailed on $5 million bail on a charge of stealing Meo’s car and being a person of interest in the case.
The search for the missing people reportedly focused on DiNardo’s parents’ property in Solebury Township, PA before his confession Thursday.
Investigators reportedly discovered a 12-foot deep grave on the property Wednesday containing the remains of multiple bodies inside.
Lang on Thursday said “as far as I know, no” when asked if DiNardo’s parents were involved in the incident.
“That’ll come in time,” he added when asked what DiNardo’s motive was, citing respect for the families impacted.
