Roderick Williams, 22, of the 3000 block of North 23rd Street is charged with homicide by vehicle, DUI and related offenses. He is also charged with simple assault and reckless endangerment for the injuries suffered by the child.
The crash happened in the southbound outer lanes of the Roosevelt Boulevard near Loney Street in Northeast Philadelphia around 11:00 p.m. Wednesday.
Officials tell Action News that Michael Romano, 43, of the 6900 block of Sylvester Street, was attempting to cross the Boulevard with his 5-year-old son when he was hit.
Romano was pronounced dead at the scene. His son was treated and released at the hospital, having only suffered a cut to his ear.
Police say they don't know where Romano was going or where he was coming from when he was hit. However, he and his wife had checked into a motel a few blocks away earlier in the night.
Romano and his son were not crossing at a crosswalk, investigators said.
Police say Williams, the driver of the striking vehicle, fled the scene. An off-duty police officer, who witnessed the accident, was able to pull over and arrest Williams a few blocks away.
Authorities add that Williams has a prior DUI conviction.
