A Pennsylvania dad faces charges after his toddler son drowned while the man was allegedly passed out drunk on his lawn.

David Gammon, 35, was charged Tuesday with involuntary manslaughter and child endangerment in the death of 2-year-old Anakin Gammon, news station WFMJ reported.

Gammon told police he had been “sipping” on a Four Loko when he took the tot and his 5-year-old brother outside in September.

While outside, he became unconscious and the children wandered away from their Sharon home, according to police.

A neighbor found Gammon asleep on the lawn after another one of his children came over saying that he couldn’t wake his dad or find the siblings.

The neighbor told police that Gammon reeked of alcohol and had difficulty understanding that his sons had disappeared, news station WKBN reported.

The two boys were reported missing and police found the 5-year-old, who has special needs, a few blocks from Gammon’s home.

But Anakin was discovered unresponsive in a backyard swimming pool about nine blocks away in Masury, Ohio.

Emergency responders attempted to revive the 2-year-old, but he was pronounced dead at the hospital.

The boy’s death was ruled a drowning.

Authorities filed charges against Gammon after investigating the death.

“There is probable cause that David Gammon was reckless in consuming enough alcohol, while caring for his children, that he lost consciousness allowing them to wander from the property,” police said in the complaint.
