Police say 17-year-old Joel Fabian Davila is on the run and should be considered "armed and dangerous" after allegedly shooting his mother's boyfriend during a fight.

The Palm Beach Sheriff's Office says Davila shot the man at the Sand & Sea Mobile Home Park on the 1600 block of NW 21st Terrace -- where police say the victim doesn't live -- before allegedly running away wearing a black baseball hat, a white and blue jacket, a white tank top, and jeans.

He's about five-foot-four and weighs 140 pounds; more information, including the status of the victim, was not available Sunday night.
