A mother was booked on a charge of first-degree murder for allegedly placing her 3-month-old son in a clothes dryer and turning it on.

The infant had third-degree burns over 50 percent of his body and suffered blunt force trauma to the head, the St. Tammany Parish coroner said.

Police Sgt. Darryl Darden said Lakeisha Adams, 18, called police to her home on Monday to report that someone had killed her child. When officers arrived, they found Jailand Adams on a sofa. He was pronounced dead at the scene.

Darden said Adams admitted during questioning to putting the infant in the dryer and turning it on, but did not say why.

Adams also has a 1-year-old child who was placed in state custody, police said.

If convicted, Adams faces death by injection or a life sentence. The first-degree murder charge is mandatory under Louisiana law because the victim was under age 12.
