SAN ANTONIO -

A man who acted as a witness in a cold case murder investigation now has admitted he took part in the crime, according to an arrest affidavit.

San Antonio police arrested Quentin Henry, 36, after he walked into their headquarters Tuesday and turned himself in. 

The affidavit stated Henry asked to speak with detectives, then confessed to taking part in the October 1997 shooting that led to the death of Kimberly Coleman, 31.

Coleman was hit by gunfire that was sprayed into the 402 Lounge on S. New Braunfels Street.

The case had been unsolved until April of last year, when detectives received word that DNA on a baseball cap found at the murder scene matched a sample from Jeremiah Barefield, 31, the affidavit stated.

Detectives said Henry was among several witnesses who they questioned last year.

They said at that time, he told them that he was in a car, watching as Barefield and Felton Jones, 32, fired shots into the East Side nightclub. Police arrested Barefield in November.

Jones was already in jail in connection with another case. Both men are currently awaiting trial in connection with Coleman’s murder.

The affidavit stated Henry told detectives Tuesday that he also fired shots into the nightclub, then took apart the 9mm weapon and disposed of it in the Rodriguez Park creek bed and Camargo Park.

Police said some of the rounds fired into the night club were from a 9mm weapon.

Henry was booked into the Bexar County jail on a murder charge with bond set at $250,000.
