John told Fox 13 that he allegedly found his brother dead when he visited his home after receiving a call from a neighbour to say a door had been left ajar.
Upon arriving at the residence, John said he found the front door locked but the back door was wide open.
“I walked in and then I found him, and I just called 911,” he told Fox 13 just hours after discovering his brother’s body.
He added that Rick still had his keys in his hand and that his pants were “pulled down to his feet”.
“I thought his coat was up over his head like it was cold or something,” John continued. “I ran out and then I ran back in. And, then I realised it was something worse.”
In his initial interview with Fox 13, John left out the graphic details of what he came upon in his brother’s home. However, on Thursday, he told the station he had found his brother’s body decapitated.
The DJ survived a shooting in 2014 after he was robbed at gunpoint outside the live music venue The Stage Shop, which was owned by his mother, Nita Makris.
He was hospitalised in critical condition and underwent several surgeries due to his injuries.
John told Fox 13 that his brother became increasingly reclusive after the shooting and had difficulty finding work.
He added that he has “no idea” whether the latest incident involving his brother was related to the 2014 shooting.
Police confirmed his death and said they are still investigating the circumstances behind it. However, there was no indication that Rick had been beheaded, with police saying there were “no immediate signs of foul play on the scene”.
“The cause of death is undetermined at this time, the department said in a post on X. “The death investigation is ongoing.”
Following his death, Rick’s family launched a GoFundMe page to raise money for the DJ’s funeral fund.
“If you knew Rick, you know he gave to anyone he could, friends, strangers, and charities like MDA,” a message posted on GoFundMe said. “He used his voice and personality to raise unthinkable amounts of money for others.”
