A 15-foot-long, two-person submarine will be used to search an Adirondack lake for the remains of a New York City man who disappeared while swimming 20 years ago.

The yellow submarine's co-owners plan to search Lake George this weekend as part of an effort organized by American Response for the Missing, a downstate group that aids in the search for missing persons.

The sub will be used to search for the remains of Edison Arias, a 23-year-old Queens resident believed to have drowned in June 1993 while swimming in about 80 feet of water off the lake's western shore in Bolton. His body was never found.

The search will also include divers assisted by the Warren County Sheriff's Office and Lake George Park Commission.
