ARLEY — Authorities say a Mississippi teenager drowned while on a church outing in Alabama.

The Alabama Law Enforcement Agency said in a statement that the 16-year-old drowned around 6:30 p.m. Saturday at Lewis Smith Lake.

The teen was swimming off a boat dock at a private residence in Arley when the drowning, said Trooper Johnathan Appling.

The victim’s football coach, Chris Craven, identified him as Thomas Lee Bales, a student at Oak Hill Academy in West Point, Mississippi. Bales was on a church trip to Smith Lake when he died.

He was about to start his junior year at the private Christian school on Monday. Bales’ father is on the school’s board.

Craven posted the following on Facebook:

A prayer vigil was held Saturday at Oak Hill Academy’s football field. Bales played football for the OHA Raiders. Prayer requests for Bales’ family circulated on Facebook feeds Saturday evening.

From Oak Hill Academy:

The Alabama Law Enforcement Agency has released no other details about the incident, and it remains under investigation.

This marks at least the second drowning at Smith Lake this summer. A 62-year-old man drowned last month while swimming off a boat dock.
