Two women shot at Pizza Hut on East 38th Street Saturday afternoon.

Erie Bureau of Police investigators on Saturday night arrested a man in the afternoon shooting that injured two women at an east Erie restaurant, Erie Police Chief Dan Spizarny said.

State police from the Girard barracks took the suspect into custody shortly before 6 p.m. on the Interstate 90 westbound lanes at mile marker 16 in Fairview Township.

Troopers saw a white Nissan Altima, which matched the description of the suspect's vehicle. When troopers put their flashing lights on, the vehicle pulled over and the suspect surrendered without incident, state police said.

Investigators questioned the man initially as a person of interest in the shooting and later arrested the suspect, police reported. The suspect is expected to be arraigned on Sunday.

Erie police were called to the Pizza Hut at 2007 E. 38th St. just after 2 p.m. on Saturday to investigate a report of a shooting. One victim was found at the restaurant with a wound to the head, while another was found across the street at the Dollar General at 2036 E. 38th St. with a shoulder wound.

Both women who were shot worked at the Pizza Hut and each is her 20s, Spizarny said.

"We are leaning toward the potential that it was a domestic situation," Spizarny said.

The women who suffered the gunshot wound to her head was in critical condition in the intensive-care unit at UPMC Hamot on Saturday night, police reported.

Investigators believe both women were shot inside the restaurant, Spizarny said.

State police searched multiple areas in Erie County, including areas in Summit Township, before they apprehended the suspect, authorities said.

The woman with the shoulder wound was conscious when she was taken to UPMC Hamot for treatment.

The woman who suffered the shoulder wound fled the restaurant and ran across East 38th Street to the Dollar General store to seek help and report the shooting, Spizarny said.

Police identified the shooting suspect as a Hispanic male wearing a black hooded sweatshirt, black pants and a white hat.

"A person of interest was brought to the station and is being questioned," Spizarny said on Saturday evening.

Police cordoned off the entire restaurant with police tape, as well as the entrance to the Dollar General. The entire perimeter of the Pizza Hut remained cordoned off Saturday night as police processed the scene for evidence.
