Killeen teenagers Aireal Caballero, 15 (left), and Braelyn O'Neal, 13 (right),  were last seen on May 8, 2016.

Cabellero is described as a Hispanic girl with light brown hair and brown eyes, 5'4" tall, and weighing 140 pounds.

O'Neal is a white girl with light brown hair and green eyes, 5'1" tall, weighing 145 pounds.

Both are said to have been in the company of another juvenile female, but it is unclear if they were or are together.
