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.

“We honor the service and sacrifices of Officers Brian Sicknick, Howard Liebengood, and Jeffery Smith, and offer condolences to all the grieving families,” Contee said in his testimony.
