Original release (May 6, 2016 2:10 p.m.):
Baltimore County Police seek the public's help finding a Lutherville man missing since last week despite an extensive search by law enforcement.
Brian Keith Wallen, 52, of the 500 block of Wyngate Rd., is considered a "critical" missing person because investigators believe he may be suicidal.
Wallen, who is white, is 6' tall and 190 pounds; he is bald and has blue eyes. He was last seen wearing khaki shorts, a ball cap, blue T-shirt and sweatshirt of unknown color.
Police began searching for Wallen on April 28 after Wallen's lawyer called to report that he had received what sounded like a "goodbye" letter from his client. Police responded to the Wyngate Road home, where they found a suicide note.
Police also found Wallen's silver Jeep, unoccupied and locked at the Fire Trail at Loch Raven Reservoir between Surrey and Old Bosley roads. An exhaustive search of the reservoir and surrounding area has since been conducted by BCoPD's Tactical Unit, K-9 Unit, Air Unit, Baltimore Environmental Police and search dogs from Mason Dixon Rescue Dogs Inc. and Chesapeake Search Dogs. This search has revealed no trace of Wallen.
Anyone with information about this case should contact BCoPD as soon as possible, 410-307-2020.
