(AP) — Omaha police say a man has been arrested in connection with the October death of his girlfriend’s infant son.

Police spokesman James Shade says 27-year-old Ryan Mullen was in custody Tuesday at the Douglas County jail. He has been charged with felony homicide-child abuse.

Prosecutors say Mullen is responsible for the death of 8-month-old Payton Birtwell. The boy was brought to a local hospital on Oct. 18 after his mother told officers her son fell out of his stroller. Payton had a brain bleed and was taken off life support several days later.

Court records do not list if Mullen has an attorney.
