Steven Douglas Geisler, 51, was last seen May 10, 2013, in Phelan, California and vanished under suspicious circumstances. On May 18, 2013 his white 2002 Ford F-250 pickup was found abandoned along Fire Service Road 3N05 near Lytle Creek Road, roughly 30 miles from Phelan. Searches of the area turned up no sign of Geisler.

He is described as 5 feet 8 inches to 5 feet 10 inches, about 190 pounds, with sandy light brown hair and blue-green eyes. The Stockton Police Department is listed as investigating, though the available details do not explain why Stockton authorities are involved. Few other facts have emerged since 2013.

Does anyone who knew Steven or who was in the Phelan or Lytle Creek area that week have information to share with investigators?
