RUTLEDGE, Tenn. (WVLT) -- A Knoxville man who was arrested on Monday on charges he threatened to kill his wife and himself at a Blaine doctor's office was committed to a mental institution, according to Grainger Co. Sheriff Scott Layel. Christopher Britt was transferred to Peninsula Mental Institution around 4:00 a.m. on Tuesday and remains there.

The 48 year-old and his wife were both waiting on appointments at Cherokee Health Systems' Blaine Medical Center when they got into an argument. Christopher reportedly became enraged and irrational. He then allegedly told his he was returning home to get a gun and come back to shoot her and himself.

Grainger Co. deputies though caught up to Britt at his Knoxville home and arrested him.

It was the second time in a week that Blaine Medical Center, 180 Emory Road, was evacuated and closed down. On the previous Wednesday, the Grainger Co. Sheriff's Office said Dr. John Neece was held hostage at knife point by Verne Long, who was threatening to cut the doctor and himself. Long was eventually caught after officers forced their way into the room.

"This incident leads me to believe that this individual may have had a copycat scheme in mind," said Layel. "He made the statement that what happened here last week would be nothing to what's going to happen today."
