There were two main actors in the weekend stabbing of 26-year-old Good Samaritan Terrell Cowherd on Lower Greenville, police say: Jerry Brown, 23, who punched Cowherd, then held him from behind, and Julian Terence Martin Jr., also 23, who repeatedly plunged his knife blade in Cowherd's torso. Both men were arrested and charged with murder.
A third man, 21-year-old Rodney Williams, came forward the day after the stabbing and admitted to a Dallas police detective that he'd been an accomplice.
According to an arrest affidavit, Williams admitted to holding back the crowd of onlookers and stopping anyone who might have otherwise come to Cowherd's aid as he was repeatedly stabbed.
He also confessed to piloting Martin away from the crime scene in his Mercury Grand Marquis, which was confirmed by surveillance footage from a nearby business. He also said he had scrubbed the car clean of Cowherd's blood, which Martin had apparently tracked in.
Williams, however, wasn't arrested on Saturday. He turned himself in to police on Wednesday night and, like Martin and Brown, now faces a murder charge. He's in Lew Sterrett on a $500,000 bond.
