UPDATE: Court documents have released more details into the death of Clayton Stephens and the man accused of killing him, Tawann Richardon, 24.

According to those documents, Stephens and Richardson were in a secret romantic relationship which may have been a reason for the killing.

Stephens was found dead with a gunshot wound to his face on April 9 near SW 38th and Coombs.

Investigators say Stephens’ friends told police they had not seen him since the night before when he left a home they were at and said he would be back.

During the investigation, Vernon, Texas police found an abandoned Chrysler Pacifica abandoned in their town which belonged to Richardson’s pregnant juvenile girlfriend. After receiving a search warrant, police say they found blood inside and outside the vehicle.

Police then reviewed surveillance video from homes near where Richardson and his girlfriend had been staying which showed Richardson getting into the Pacifica the night Stephens died. When Richardson returned, he had removed a jacket and shirt he was originally wearing.

Documents say police found messages between the two that showed Stephens was angry with Richardson having relations with him and his girlfriend and threatened to reveal their relationship. This was reportedly met with “hostility” by Richardson.

Police say the last contact in Stephens’ phone was a one minute call to Richardson.
