Ryan Walsh, a former litigation associate at Bryan Cave who was laid off six months after joining the firm in 2008, admitted in a federal court in St. Louis this week that he once threatened to kill a former colleague on a 2013 phone call.

The St. Louis Post-Dispatch reported Wednesday that Walsh, 32, pleaded guilty to one federal charge of transmitting a threat via interstate commerce to a Bryan Cave partner in the firm’s St. Louis office. Walsh left the threat on the unidentified partner’s office line at 9:27 p.m. on June 15, 2013, according to The Am Law Daily’s previous report on his indictment three years ago.
