An MTA worker and mother of six, who police say was killed in Brooklyn by her ex-boyfriend, was shot dead on her daughter's birthday.

Jacqueline Dicks, 41, told relatives Monday that she wanted to see her daughter Terrena Drumgold before midnight, so she could wish her a happy 16th birthday. She never got the chance.

Zire King, 44, shot her in the head about 11:40 p.m. Monday in East New York, police said. Cops were still hunting for King late Thursday. Police said a gun found in the suspect's car was the murder weapon.
