An Atlanta man is still missing and believed drowned after jumping from a sailboat into Lake Lanier early Saturday morning. 

WSB-TV reported that Jeffrey Nause, 44, jumped from a sailboat into the lake waters about 12:30 a.m. Saturday. He was with a woman and another couple near Lake Lanier Islands.

Georgia Department of Natural Resources officials (DNR) officials said they had to suspend the search Saturday due to the high volume of traffic on the lake, and the search was expected to resume Sunday. DNR spokesperson Mike Burgamy said alcohol may have been a factor in this case, which is being investigated by the DNR and the Hall County Sheriff’s Office.

The Atlanta Journal-Constitution reported that the case is being investigated as an accidental drowning.

Nause is a Georgia Tech alumnus and the CEO of a semi-conductor company, Cermet, Inc., located at 1019 Collier Road in Buckhead. The father of two is a native of Mississippi.
