A US Capitol police officer who responded to the mob riots in Washington on Wednesday, died days after the violence, according to a statement by the Capitol police on Sunday.
Two law enforcement officials claimed Liebengood, 51, had died by suicide over the weekend, reported The Washington Post.

"We are reeling from the death of Officer Liebengood... Every Capitol Police Officer put the security of others before their own safety and Officer Liebengood was an example of the selfless service that is the hallmark of USCP. This is a tragic day," said Gus Papathanasiou, head of the Capitol Police union, said in a statement.
Friends described Liebengood as humble and reserved, and said he shared a love of race car driving with his father, The Washington Post reported.
