He was rushed to the hospital but later died of extensive blood loss. Charles had been stabbed about eight times in the abdomen, chest, groin, and cuts on the face, scalp, and other areas.

The authorities learned from Leigh about a loud party that was going on in the house next door. Sometime during the early hours of April 18, someone from that party had urinated on Charles’ home. When he returned home, the 36-year-old decided to go up there to talk about it. As per the show, Charles didn’t come back, and Leigh found him sometime later, alone and bleeding some distance away from the house.

The police followed a blood trail that ended at a nearby fence, confirming Charles was attacked there. According to the show, they searched the house next door and saw blood on the doorknob and in the bathroom. Furthermore, there was a knife in the kitchen sink that the authorities believed could be the murder weapon. Upon investigation, they learned that John Martinez and his girlfriend lived in that house but were nowhere to be seen that night.

Eventually, the girlfriend was tracked down but claimed to know nothing about the attack. However, a witness from the party told the police that after Charles came by to talk about someone urinating on his garage door, John got into an argument with him. Later, he went into the house and returned with a knife. John then chased after Charles, and the belief was that the former stabbed the latter after catching up to him.

As per the show, John asked Gregory to drop him off at his grandfather’s house the next day. Eventually, John turned himself in but refused to cooperate. However, the evidence against him was enough for the prosecution to build a solid case.
