A grandfather sits in jail, accused of leaving his two young grandchildren alone for hours.

London police arrested Doyle Cook, Junior of Alaska, after an employee noticed Cook's three-year old granddaughter wandering alone outside by the pool at the Days Inn on Highway 80.

Then, housekeepers say they found his seven-year-old grandson alone in the room.

When Cook returned, he told police he was visiting friends in Mt. Vernon.

"There is just no excuse for leaving that small of children alone for any period of time," said Angela Schafer, the hotel employee who found the children.

"When he got back, he scolded the children for calling the police, but they didn't, I did," Schafer said.

Cook is charged with two counts of endangering the welfare of a minor. The children are now in the custody of child protective services.
