A US mother has drowned her two youngest sons by sitting on them in the bathtub because voices in her head told her to so that she could be a better mum to her eldest boy.

Laurel Michelle Schlemmer, 40, never attempted CPR when she pulled the limp bodies of her sons Daniel, 6, and Luke, 3, out of the bathtub in their Pennsylvania home last week.Instead, she stripped off their wet clothes and placed the items in a garbage bag before phoning emergency services and in a “sweetly high-pitched” voice calmly said that her sons may have drowned while playing, according to a 911 tape leaked to the Pittsburgh Post-Gazette.”I think that they’ve – they’ve drowned in our bathtub,” she reportedly said.Before the drownings, she took her oldest son, 7, to the school bus.It’s alleged she later confessed to the drownings when interviewed by police, telling them: “They would be better off in heaven.”

Luke died hours after being rushed to a Pittsburgh hospital on Tuesday.

Daniel, who had been on life support, was pronounced dead on Saturday.

Their mother has been charged with homicide, attempted homicide, aggravated assault and child endangerment, but those charges are expected to change following her second son’s death.

Schlemmer is being held in Allegheny County Jail in Pittsburgh and is on suicide watch, WXPI-TV reports.
