Ogden Police Department officials said the man encountered the young girl just before 6 p.m., according to CW39 Houston sister station KSTU in Salt Lake City.
Marcus King told the station he was on his way to play some pickup basketball when a little girl called out to him from a playground near the Marshall White Community Center, 222 28th Street in Ogden.
“I had heard a little girl’s voice inside the park, didn't really think nothing of it... once I came around this way she had got my attention,” he said.
The girl was playing in the snow on the playground, but with the sun already down and temperatures near freezing, King was shocked by her attire.
“She didn’t have any jacket, no shoes, no parental supervision, and just took action then and took her inside,” he said.
The staff at the nearby community center helped him call police, and King stayed around for almost three hours until police could figure out where the girl’s mother was.
“When they walked over there, the door was wide open," King said. "And the way the little girl was explaining it was: Her mom wasn't paying attention, and her mom was on the floor sleeping.'
Police confirm the girl’s mother died nearly 24 hours earlier. At some point the young girl left the apartment and went across the street to the playground.
Investigators did not confirm any specific details about the cause and manner of the woman's death.
King told the station he was glad to help out a child in need.
“This is not a good part of Ogden—there’s a lot of weirdos around here, and I’m really, really fortunate and happy that I got to her, and nobody else did,” he said.
As of Thursday night, the child was in the care of the Division of Child and Family Services and authorities were working to determine if there are relatives she can stay with.
