A Louisiana father was arrested for murder after he allegedly left his infant daughter inside a car for more than nine hours on a day where temperatures reached over 100 degrees.

Joseph Boatman, 32, was detained Sunday after his 21-month-old daughter was left buckled inside a car in the Madisonville-area for hours on end.

Deputies with the St. Tammany Parish Sheriff's Office were called to a residence just before noon after a family member found the baby unresponsive inside the vehicle, police said.

Authorities soon discovered that Boatman picked his daughter up from a family member's home earlier that morning after he 'consumed multiple alcoholic beverages.'

He then strapped his child into a car seat around 2.30am and 'went back inside the residence and never returned to the vehicle,' police said.
