“Right now, we’re trying to figure out what happened,” said Sgt. David St. Pierre moments after the second pedestrian was hit, attended to by ambulance personnel and taken to Central Maine Medical Center.

Police said Deshaun Jackson, 23, was crossing Pine Street at around 1 p.m. when he was hit by a man driving a tan Chrysler. “We don’t know the extent of his injuries yet, but at some point he went unconscious.” Police said Jackson was being evaluated at the hospital Saturday night.

Jeffrey Cahill, 55, of Lewiston was driving the vehicle that struck him, police said.

Eyewitness Roberta Ishola — who said she knew Jackson — said he was crossing the street in a crosswalk when the vehicle struck him. She spoke to him  immediately after he was struck, she said.

“He said he couldn’t feel from the neck down, then said he was in a lot of pain,” Ishola said. “I asked for his phone number; I was going to call his dad. The next thing I know, he was out.”

Police said the pedestrian accident was one of two, just moments apart, in the downtown neighborhood.

The other pedestrian struck by a vehicle was a young Somali boy, Hamza Muhumed, 6, of Lewiston, police said. That accident happened at 237 Lisbon St., less than a block from the other accident.

“He was brought to CMMC, as well. He was alert and conscious,” St. Pierre said.

The boy was being evaluated at the hospital Saturday night. The driver of the vehicle that struck him was Maria Fassio, 48, of Brunswick.

Police did not have further details Saturday night. Both accidents were under investigation.
