OBION COUNTY, Tenn. – The Tennessee Bureau of Investigation is looking for a 70-year-old man considered a person of interest in a double murder at Reelfoot Lake in Obion County early Monday morning.

Special agents with the TBI said David Vowell of Martin should be considered armed and dangerous. TBI said Vowell has no prior criminal record in Tennessee.

The TBI said Chance Black, 26, and Zachery Grooms, 25, both of Weakley County, were killed in an incident that occurred on Reelfoot Lake in the northwest corner of Tennesee.

Weakley County authorities said the men were out hunting and confirmed that Black was the son of Chief Deputy Mark Black with the Weakley County Sheriff’s Department.

District Attorney Tommy Thomas confirmed Tuesday that both men were shot at a blind on Reelfoot Lake.

Black was a manager in the gun department at Final Flight Outfitters, a sporting goods store in Union City, Tennessee, a representative for the store said Tuesday. The store said he was killed with his friend while they were duck hunting.

“What has taken place is hard to process. No duck is worth the life of a man. What we do know is that God is our refuge and strength, even in the hardest of times,” marketing manager Seth Dortch said in a statement sent to WREG.

The TBI is asking anyone who was near the north end of Reelfoot Lake that morning and heard or saw anything that might help agents to call 1-800-TBI-FIND.
