Authorities in Tennessee are combing through the wilderness trying to find a military special forces veteran with "extensive training in survival tactics" accused of shooting his wife.

Deputies responded the morning of May 1 at about 1:30 a.m. after Craig Berry allegedly shot his wife during a "domestic altercation" and then fled into the woods, according to the Stewart County Sheriff's Office. Berry is believed to be armed and dangerous, and "very familiar" with the area, the sheriff's office said. He was still on the run as of May 4.

Berry has a warrant for second-degree attempted murder for the shooting of his wife, officials said. Berry's wife was taken to a medical facility, and her condition was not made public.

The sheriff's office and other law enforcement agencies searched the woods and surrounding areas, starting with Gray's Landing to Highway 232 and River Trace Road in Dover, Tennessee, in the northwestern part of the state.

A trail camera picked up an image of Berry in the wooded area wearing camouflage, officials said.
