AVONDALE, La. (AP) — A 22-year-old man and his 19-year-old girlfriend were shot and killed in their car while their 4-year-old girl and 4-month-old boy were in the back seat, Jefferson Parish Sheriff Newell Normand said.

Willie Odom of Harvey and Shawna Girod of Avondale were killed as they drove to the Avondale house about 1 a.m. Saturday, he said.

Investigators say more than a dozen bullets hit the car, but did not hit the children.

Deputies were called to a car accident and found the Honda Accord in grass just off the road, with both adults slumped over. Investigators don't know why they were killed, and don't have suspects.

The girl was Odom's daughter by an earlier girlfriend, and the boy was Odom's and Girod's son, officials said. They were brought to the home of Odom's mother, Brenda Odom.
