Dallas police say DNA evidence led them to the suspect in an eight-year-old murder case.
Detectives say 35-year-old Jojo Wilson severely beat Eliazar Flores in September of 2007 and stole his truck.
Flores later died from his injuries.
Investigators saved DNA swabs from the scene and a match was made in August of this year. Police interviewed Wilson, who was already in the Dallas County jail on unrelated charges.
Wilson is now charged with capital murder.
