A 19-year-old man was booked in the death of a fetus after he accidentally shot a pregnant woman and killed her unborn baby, authorities said.

Wilbert L. Luke Jr. shot Shawntell Walker, 17, in the abdomen Sunday while he was showing her a handgun, Jefferson Parish sheriff's deputies said.

Luke drove Walker, who was 22 weeks pregnant, to West Jefferson Medical Center, said sheriff's spokesman Col. John Fortunato. The fetus died during surgery, he said.

A .22-caliber handgun recovered from Luke had been stolen in St. Tammany Parish, Fortunato said. Luke said he bought the gun on the streets about a year ago, Fortunato said.

Luke was booked with third-degree feticide and possession of a stolen firearm.
