A homeless man was on the run Sunday after he allegedly shot to death one employee and injured another at the shelter where he formerly reside.

Police said the shooter was "a prior resident of the shelter." 

The shooting reportedly occurred at 6:13 a.m. inside the Station House Men's Shelter in North Philly and left a black male in his early 40s dead and a 26-year-old black male injured with a gunshot to the hip.

The shooter was evicted from the shelter, and got into an argument with the shelter workers when he returned to get his belongings, before shooting both of them, the Daily News reported.
