Missing 3-year-old's father refused to tell police her whereabouts, police say

CHICAGO (WLS) -- Chicago police are asking for help finding a 3-year-old girl who has been missing since last July.

Investigators say Kaylin Tucker was last seen with her father just before he started serving a prison sentence. He has reportedly refused to tell police who he left her with.

A judge granted custody to the girl's mother in November.

Tucker is described as 3-foot-tall African American girl weighing around 35 pounds with brown eyes and black hair.

Anyone with information is asked to contact Chicago police at 312-747-8380.
