HOUSTON (AP) — DNA has linked a newly freed inmate to the 2006 slaying of an alleged accomplice in a Houston-area utility and robbery scam.

The Harris County Sheriff's Office on Thursday announced Alvin Wiltz has been charged with capital murder.

Wiltz was arrested Wednesday — a day after being released from prison in a drug case. Online jail records don't list an attorney for Wiltz, who's being held without bond in the slaying of Jermaine Clemons.

Homeowner Oscar Richmond awoke when Clemons knocked on his door, falsely claimed to be a utility worker and told him to evacuate due to a gas leak. Richmond knew his neighborhood didn't have natural gas and he got his gun.

The pair fought before a second suspect opened fire — wounding Richmond and fatally shooting Clemons.
