GRAHAM (AP) – Police documents obtained by The Associated Press say a North Texas father called 911 and said he had killed his children, an infant and toddler who were found dead about 10 hours later.

Police in Graham say they verified the call was from 28-year-old Gabriel Armandariz’s cell phone.

Police say they had started investigating Wednesday after Armandariz’s sister reported seeing a cell phone picture showing what appeared to be the dead infant.

Police say the man called 911 and confessed later that day.
