WALKER (AP) -- A central Minnesota man is being held on $1 million bond in the death of an infant in his care.

Twenty-year-old Presley Sleyster is charged in Cass County with second-degree murder without intent in the Dec. 5 death of the three-month-old boy.

Sheriff's deputies were called to Sleyster's rural Staples home for an infant who suffered a seizure and was not breathing. The child was taken to Children's Hospital in Minneapolis where he died two days later. A medical examiner determined the boy died of homicide from blunt force trauma to his head.

Sleyster told investigators he didn't know how the baby was hurt but said it was possible he may have hit his head on a stairway or door frame.
