An Ohio 2-year-old drowned in a neighbor’s Pool after he roamed from his home as his Mother slept and his father was at work, authorities said.

Toddler Marcus Hall was found at the bottom of the nearby above-ground pool Wednesday by local police after the boy’s frantic mother couldn’t find him, WTVG reported.

The child – nicknamed Mar Mar – was rushed to the hospital and pronounced dead.

Anthony Hall, Marcus’ devastated father, told the station the 2-year-old and his 4-year-old brother were home in the city of Oregon in the Buckeye State with their sleeping mom when both kids got out of the house.

A neighbor called 911 around 10:30 a.m. to report a baby in a diaper chasing a dog without an adult around, according to audio from the dispatch obtained by the outlet.

An officer reached the scene and spoke to the mother, advising her to possibly put in safety devices, police reportedly said.

But an hour later, the mother called the police for help as she looked for little Marcus.

“I got woken up to the cops over here knocking on my door because they said that kids were running around outside, so when I woke up, it’s only my 4-year-old here,” the worried mother said, with the dispatcher replying, “So your 2-year-old is missing?”

“Yeah,” the mother said, according to WTVG.

When the tot was found in the pool, one officer jumped in to retrieve him and another officer quickly performed CPR before he went to the hospital.

“He was a cool little dude, like,” Anthony Hall said before he became too choked up to continue. He remembered his son for his smile.

A violation was listed against the neighbor’s pool because it is supposed to have a fence around it, and Child Services is looking into the case, the station reported.
