SEQUOYAH COUNTY, Oklahoma - Investigators need help as they look into an ATV crash that's left a Green Country teen in the hospital for nearly five months.

They've set up a tip line for anyone with information on what happened to 16-year-old Christian Mayberry. The initial highway patrol report said he was alone driving the ATV and crashed outside Muldrow.

But his mother said she heard one of his friend's mothers was driving, and she was drunk.

After the crash, Mayberry was thrown in a ditch and left for hours before he got any help.

If you know anything that can help in the investigation, call 918-822-2901.
