Amber Alert canceled in Texas for 2 girls possibly taken by person of interest in mom's murder, police say

ROUND ROCK, Texas -- An Amber Alert was discontinued in Texas Wednesday for two girls who may have been kidnapped by a man connected to their mother's murder, police said.

Police in Round Rock, which is near Austin, said Wednesday that while the alert was canceled in Texas, it will still be active in other states because they have evidence that indicates the children may be in another state.

Tonya Bates was found dead Sunday in her home in Round Rock. Her two daughters were missing. Bates' neighbors said police had been to the home before, for a domestic disturbance.

Investigators said they believe 7-year-old Luluvioletta Mariposo Bandera-Margaret and 14-year-old Lilianais Victoria Cake Griffith were taken by Bates' roommate, 44-year-old Terry Allen Miles.

Lilianais is described as a white female, 5 ft. 0 in., 100 lbs. with light brown hair and brown eyes. She also has a stud on the right side of her nose. Luluvioletta is described as a white female, 4 ft. 5 in., 75 lbs. with brown hair and brown eyes.

Police are looking for Miles, who they believe may be connected to Bates' death. He is believed to be driving a gray 2017 Hyundai Accent with TX license plate: JGH9845.

Miles was last seen in Round Rock on Saturday and may be heading to Louisiana, police said. His last known location was somewhere in northern New Mexico or southern Colorado.

Law enforcement officials believe the girls are in grave or immediate danger.

Anyone with information is asked to contact the Round Rock Police Department at 512-218-5516.
