A second police officer who responded to the violent insurrection that rocked the Capitol Building on Jan. 6 has died by suicide, according to testimony obtained by POLITICO.

Acting Metropolitan Police Chief Robert Contee told House appropriators during a closed-door session on Tuesday that Jeffrey Smith, a D.C. Police officer, and Capitol Police Officer Howard Liebengood both “took their own lives in the aftermath of that battle.” Smith’s death had not been disclosed prior to Contee’s testimony.

A third member of law enforcement, Capitol Police Officer Brian Sicknick, died from injuries he sustained during the Capitol attack.
