LUBBOCK, Texas—Authorities have found a missing East Texas teenager who had been the subject of a multistate Amber Alert.

Lubbock police say 15-year-old Nomei "Mimi" Valazquez has been found unharmed. Police Sgt. Jason Lewis said the Nacogdoches, Texas, girl was found at a Lubbock residence on Wednesday. A 28-year-old construction worker has been taken into custody. There was no word on if he had been charged Wednesday.

Velazquez has been missing from Nacogdoches since Monday.

Investigators had said a ping of the girl's cellphone indicated she and the man were in Kansas, then later in Lubbock.
