DENVER (CBS4)– The sister of teenage arson suspect Kevin Bui, arrested in connection with a deadly house fire that killed five, will also face charges in connection to the arson. Tanya Bui appeared in court on Wednesday on drug and weapons charges and pleaded not guilty.

She remained in custody after her court appearance on charges of possession of marijuana with intent to distribute, as well as possession of a firearm in furtherance of a drug trafficking offense.READ MORE: City Park Jazz Announces Its 2021 Summer Lineup
