BALTIMORE —  A man killed his three young children at a downtown hotel Sunday, then called the front desk to report the killings, police said.

Mark Castillo, 41, of Silver Spring, called the desk at the Baltimore Marriott Inner Harbor at Camden Yards at about 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 a 10th-floor room and found three children dead and Castillo with minor cuts that appeared to have been self-inflicted, Clifford said. He did know how the children were killed.

Castillo was taken to a hospital for treatment of the cuts and is in police custody.

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

Silver Spring is about 35 miles south of Baltimore.
