Texas police are asking for the public’s help in finding two young sisters believed to be with a person of interest in the suspicious death of their mother, PEOPLE confirms.

Round Rock, Texas, police announced on Sunday they are searching for Lilianais Griffith, 14, and Luluvioletta Bandera-magret, 7, a police spokesperson tells PEOPLE. The girls were reported missing after their mother was found dead under “suspicious” circumstances that day, according to a police spokesperson.

Police believe the girls are with 44-year-old Terry Miles, who was living with the girls and their mother, the spokesperson tells PEOPLE.

On Saturday, police responded to a welfare check at the girls’ home but the home appeared to be empty, Chief Allen Banks said at a press conference on Monday. The following day, authorities returned to the home, where upon entering they discovered the body of Tonya Bates, 44.
