HOUSTON -

Houston police said they have solved a murder that happened eight years ago.

Christopher Rolando Watson, 39, is charged with murder.

HPD said Watson killed Shannon Stack, 33, on April 19, 2006.

Investigators said Stack was visiting an ex-girlfriend at her home on Club Creek Drive and became involved in an argument with Watson. When the woman left the room, police said Watson shot Stack. The woman said she found Stack on the floor of the living room with a gunshot wound to the chest.

HPD said they arrested Watson Wednesday after new evidence pointing to him became available.
