Yet Another Toddler Accidentally Shot And Killed His Mother

A 2-year-old boy accidentally shot and killed his mother on Tuesday while she was driving in Milwaukee, Wisconsin. It adds to a growing list of accidental shootings by toddlers.

Patrice Price, 26, was driving her security guard boyfriend's car on Highway 175 when the 2-year-old fatally shot her in the back with a single bullet.

Her boyfriend had left his gun under the driver's seat. It slid out and her young son in the backseat grabbed it, Milwaukee County Sheriff's Office said in a statement. Price's 1-year-old child was in the front seat when the shooting happened.

Price was unresponsive when authorities arrived on the scene and was pronounced dead on the scene.

"My chest has been hurting," the victim's father Andre Price told WISN. "I wanted to hold my daughter for one last time."

Accidental shootings -- where the victim is often the child who shot the gun -- have become frighteningly commonplace.

At least 69 children aged 17 and younger had picked up a gun and accidentally shot someone so far this year, according to data from gun control advocacy group Everytown for Gun Safety, issued before this latest tragedy. At least 265 kids were responsible for accidental shootings in 2015.

"More than two-thirds of these tragedies could be avoided if gun owners stored their guns responsibly and prevented children from accessing them," Everytown said.
