UPDATE: (CNN) Baltimore police say three children found dead in a hotel room on Sunday had been drowned in the bathtub by their father.

Police Commissioner Frederick Bealefeld said Monday morning that the father is in custody at a hospital. Police say Mark A. Castillo, of Rockville, Maryland, will be charged after he is released. He is being treated for self-inflicted cuts on his neck.

BALTIMORE (AP) -- A Montgomery County man killed his three young children at a downtown hotel, then called the front desk, according to Baltimore police.

The man, identified as Mark Castillo, 41, of Silver Spring, called the desk at the Baltimore Marriott Inner Harbor at Camden Yards around 1:15 p.m. Sunday and said he had just killed his two sons and daughter, said police spokesman Sterling Clifford. Police identified the children as Anthony, 6, Austin, 4, and Athena, 2.

After hotel security called police, Clifford said officers went to the 10th-floor room and found three children dead and a man with minor cuts that appear to be self-inflicted. Clifford did not have details on how the children were killed. He said the children's bodies were still at the hotel Sunday evening.

Castillo was taken to a hospital for treatment of the cuts and was being questioned by police Sunday evening, he said.

"Why he brought them here to do this, is something we don't know yet," Clifford said.

The children's mother was notified, but details about custody of the children was not yet clear, Clifford said.

Many guests at the hotel on Sunday were unaware of what had happened, particularly because the killings took place on the top floor.

The only clues that something out of the ordinary was going on were a few television trucks parked outside and a police officer by the elevator bank asking guests what floor they were heading to.
