TUCSON, Ariz. -- The parents of 18-month-old twins in Tucson are in custody on suspicion of child abuse.
Tucson police said Thursday that 25-year-old Kristepher Benavidez and 30-year-old Monique Gaxiola have been booked into Pima County jail.
Bond for Benavidez is set at $20,000 and $5,000 for Gaxiola.
Tucson Fire Department personnel went to a home in response to a child not breathing call about 2:30 p.m. Wednesday.
They took the toddler to a hospital and police found the toddler's twin and a 7-year-old sister at a neighbor's home.
Officers say the older child appeared uninjured, but the twins had injuries that appeared non-accidental.
Detectives say it appears Benavidez had been physically abusing the twins for an unknown period.
They say Gaxiola allegedly was aware of the abuse, but didn't report it.
