The FBI has added a big 2019 California murder suspect to its Ten Most Wanted Fugitive list.

Omar Alexander Cardenas, 27, is accused of gunning down Jabali Dumas, 46, at an outdoor shopping center in Sylmar, just north of Los Angeles, on Aug. 15, 2019, according to authorities.

Cardenas is seen on surveillance video walking into the parking lot, reaching into the back of his waistband. Just over a minute later he appears again, running away.

Los Angeles police allege that the two men got in a verbal argument before Cardenas went to his car and came back with a gun to kill the victim.
