Bertram Clark kills girlfriend as her children watch

From CBS Miami:

Miami police are hunting a man on the lam after he allegedly shot his wife in front of her children, and left her to die in a pool of blood.

Police are trying to find 42-year-old Bertram Clark, last seen running out of the apartment of 25-year-old Shanquendra Quenishea Williams in the 1200 block of NW First place in Miami, shortly after midnight Monday morning.

Miami police spokesperson Det. Willie Moreno said Clark and Williams had argued before he left her apartment. Williams apparently called police and Clark, who lives nearby, returned to her apartment, angry about the call.

Investigators say Clark apparently pulled out his gun and pistol-whipped Williams while her children watched. As his anger grew, police said he used the pistol to shoot her, multiple times, with the children in the room, before running out.
