Air Force officials say missing 21-year-old airman Keifer Huhman (below) drowned in the Dover Delaware canal system last month, although his body has yet to be found.
Huhman has been gone without a trace since February 7th, when he reportedly phoned friends to cancel previous plans to attend their Super Bowl party.
His truck was towed from the northbound side of the Route-1 bridge spanning the C&D Canal several days later, according to police reports.
Investigators also discovered overturned furniture in Huhman's apartment, but haven't said if the disarray found there is connected to his disappearance.
His truck was towed from the northbound side of the Route-1 bridge spanning the C&D Canal several days later, according to police reports.

He was expecting to transfer soon to the Okinawa air base in Japan where his father, Chief Master Sergeant Kenneth Huhman, was stationed.
It was an appointment Keifer Huhman was evidently looking forward to, but this week three officers of the Dover Air Force Base notified the missing young man's mother in person that her son is now "considered deceased."
They further promised "in writing" to assist the coroner in promptly issuing a death certificate stating he died when he "fell off the bridge" so the family can finally obtain "closure," she told reporters yesterday.
"We are continuing to ask everyone located within the C&D canal area to keep a lookout in and around the water," a relative also posted on Facebook. "Due to the waterway’s temperatures and extremely dangerous conditions, Keifer may not be found until the water warms up."
However, a spokesman for the Dover Police Department has emphasized that their own probe into Keifer Huhman's unsolved disappearance remains open and active.
"It's still being investigated as a missing persons case at this time," he said.
Anyone who knows what happened to Senior Airman Huhman over a month ago, or knowledge of his current whereabouts, is urged to contact the DPD at (302) 736-7130.
