A man, who was shot in the mouth after pistol-whipping his father, is jailed this morning on a domestic-violence charge, Marshall County authorities said.

When deputies responded to a shooting call at a home on Martling Gap Road, they learned that the 52-year-old Randall Allen Whitten had pistol-whipped his 73-year-old father, said sheriff's spokesman Heath Thomas. The father then shot his son in the mouth with a small-caliber handgun, the sheriff's office said.

The fight and shooting happened when the son, who is from Crossville, went to the father's house. Both men were taken to hospitals for treatment.

The son was booked into the Marshall County jail this morning on a felony domestic-violence charge. It's unclear whether the father also will be charged.

"This case remains under investigation this morning," Thomas said in a news release.

Updated at 10:35 a.m. to show the son has been arrested.
