SOUTH SAN FRANCISCO — Police arrested an Oakland woman after she allegedly shot her estranged husband in the buttocks on Saturday in South San Francisco, police said Sunday.

Monica Solorio, 29, is expected to face attempted murder and related charges after an argument with Hayward resident Sandro Delgadillo-Paredes, 31, erupted in gunfire, police said.

Officers responded around 11:30 a.m. to reports of multiple gunshots in the 400 block of Railroad Avenue, police said.

Officers arrived to find Delgadillo-Paredes suffering from a gunshot wound to his buttocks, said South San Francisco police Sgt. Sean Curmi. Medical crews transported the man to a trauma center. He is expected to fully recover, Curmi said.

Solorio was there with Delgadillo-Paredes and another adult when police arrived, Curmi said. Investigators determined Solorio and Delgadillo-Paredes were arguing when Solorio allegedly took out a handgun and shot him.

There were no other injuries.
