A second victim has died from injuries suffered in a midday shootout at a Sacramento strip mall that also killed a mother who was loading her 2-year-old son into an SUV, sheriff's officials said Wednesday.

Marvion Barksdale, 20, died after being taken to the hospital where he under went surgery Tuesday for a chest wound, Sacramento County Sheriff's Sgt. Tim Curran said.

Monique Nelson, 30, died at the scene Tuesday when she was caught in the gunbattle that erupted inside a barber shop, then spilled into the parking lot of the strip mall.

Nelson had just strapped her son into his car seat when she was struck in the chest, Curran said. Her child was unharmed and has been reunited with family members, according to authorities.

Family members did not immediately return a phone message left at their business Wednesday.

Detectives believe at least one gunman entered the Fly Cuts & Styles barber shop just before 1 p.m. and began shooting. At least one person inside the shop returned fire.

"The ensuing gun battle transitioned to the parking lot where detectives believe there were multiple subjects firing multiple weapons," Curran said in a news release.

Five other men were injured in the gunfight. All are expected to survive.

A 28-year old man was wounded in the shoulder and leg. He remained hospitalized Wednesday along with a 37-year-old man who was shot in the stomach, Curran said.

A 27-year-old man who was wounded in the leg and a 20-year-old man who was shot in the chest were treated and released.

A 39-year-old man also suffered a grazing wound to the ankle and was treated by paramedics at the scene.

Authorities are still investigating the crime and say they have no motive for the shooting. They said they have not identified which of the injured victims might be suspects.
