ROUND ROCK, Texas (CBSDFW.COM) – An Amber Alert for two Central Texas girls has now been cancelled after police say they believe they are in Colorado.

Round Rock Police Chief Allen Banks says the children, 14-year old Lili Griffith and 7-year old Lulu Bandera-Magret are still missing, and the Amber Alert for the girls is still in effect in other states.

Banks told media members on Wednesday that the suspect, 44-year-old Terry Allen Miles, was seen on a surveillance camera at a store in Colorado. Banks also said they had received numerous tips that the girls and Miles had been seen together in The Centennial State.

The girls had not been seen since last weekend when police found their mother’s body at their Round Rock home.

Police say Tonya Bates’ death has been listed as ‘suspicious’ but they’re waiting for an autopsy to determine the cause.

The Amber Alert that had been issued included a search for Miles. Miles was Bates’ roommate.
