Police say a man described as a person of interest in the shooting deaths of his wife and her young daughter has been arrested in Texas.

Andrew Anthony Guerrero was found at a hotel in Denton, Texas, along with his 3-year-old son, Seth Guerrero.

Police in Kansas City, Kan., issued an Amber Alert for Seth after 23-year-old Nicolette Lyons-Reed and her 8-month-old daughter, Leah Lyons-Reed, were found shot to death in their home Sunday.

The elder Guerrero was arrested and the boy was found safe about 8:30 a.m. at a Motel 6 near Interstate 35 in Denton, about 35 miles northwest of Dallas.

Police said a truck matching the description of Guerrero's was reported at the motel at 10:45 p.m. Sunday. Police staked out the scene all night until the man emerged from his room.
