The 28-year-old father and his baby were inside a minivan parked in the 6500 block of South Maryland at 12:45 p.m. when a man reportedly came out of the alley and opened fire, police sources tell CBS 2. The father had been changing the girl’s diaper.

Police say the offender escaped in a blue conversion van.

Speaking about the at-large shooter, the girl’s grandmother, Maryann Young, had this to say: “It was very cowardly. Turn yourself in.”
