Police said they responded to the double shooting in the 6300 block of Knight Avenue around 7:25 p.m.

Paramedics declared the woman dead at the scene, according to authorities. Police identified her Wednesday afternoon as Susan Garcia, 33, of Long Beach.

The man, who’d been shot in the upper body, was taken to a local hospital in critical condition, authorities said.

Police said they took the suspected shooter into custody after witnesses at the scene detained him.

Authorities identified him as 35-year-old John McVoy, a resident of Corona. Police said they’re investigating his relationship to the victims.

Police said they booked McVoy into jail on suspicion of murder and attempted murder. He’s being held in lieu of $2 million bail, according to a news release.

A neighbor said the shooter was a member of a band that practices in the victims’ garage.

Araceli King lives across the street from the house where the shooting happened.

She said she arrived home around 7:30 p.m. and waved to a band member who was carrying his guitar toward her neighbor’s home.

Moments later, she said, he was pounding on her front door saying someone had been shot.

“‘(He) said please help us. Please help us,’” King said.

Other band members said they held the shooter until police arrived, according to King. They also brought King the couple’s child, who is about 2 years old, she said.

King said the boy kept asking for his mother, but she watched him until his grandmother arrived in tears.

“She was just crying and crying and crying,” King said.

King said she was friendly with the victims, who moved in within the last two years, but she didn’t know them well.

The neighborhood has been rocked by the violence, which is not common for the area, according to King.

“We’re all in shock. Everybody,” she said.
