Missing Teen in 'Grave Danger' After Dad Is Found Dead

Efforts to find missing teen Adriana Coronado have intensified after her father was found shot to death and burned in a Texas ditch, NBC News reports. An Amber Alert noting Adriana "is believed to be in grave or immediate danger" was issued Monday for the 13-year-old, who was last seen on Saturday in Katy with her dad, Cesar Vladimir Coronado. Authorities believe Adriana was with her father when he was murdered, and the FBI has now joined the hunt for the missing girl, the New York Daily News reports.

The elder Coronado's body was found on rural property a couple of counties away in Walker County, and his burned-out truck was discovered about 50 miles away from that location. "We're working it as if [Adriana] had been abducted," the Walker County sheriff says. Adriana's mom, who's recovering from surgery in Mexico, tells KHOU, "Please return my daughter back cause I'm dying with hurt. Oh my God. This is my only daughter, please return her to me." Adriana is said to be about 5 feet tall, 105 pounds, with black hair, brown eyes, and black-framed glasses. (A teen who set out for a fresh start has gone missing in the Atlanta area.)
