Former Lieutenant Jack Edward Travis of the LAPD, was a brutal and corrupt police officer, and the main antagonist of Lethal Weapon 3. He had a bad reputation and was brought up on charges pressed against him. One day, while Travis and a partner of his were on a stakeout, he disappeared while on the job for a cup of coffee and never came back, thus ending up going AWOL. He ended up becoming an illegal arms dealer on the black market; he used his still-valid access to the police storage to steal weapons and sell them on the street and the black market for profit. He also ran a construction company called Mesa Verde construction at Rancho Oroya. He and his gang used armor-piercing bullets, being classified by Martin Riggs and Roger Murtaugh as "Cop Killers".
