Law enforcement release sketch of 3rd suspect in Maggie Long murder

Authorities have released a sketch of a third man possibly involved in the murder of a Park County teenager.

Maggie Long, just 17, was burned alive in her family's Bailey, Colorado home in late 2017. In January of this year, authorities announced they were searching for at least three suspects in her murder, all who may have spent significant time in the home with Maggie on the day of her murder. A new task force website was launched at that time with sketches of two of the suspects. April 2, the Park County Sheriff's Office released the sketch of the third.

Maggie's remains were

one week after she was reported missing. Family members feared the worst when Maggie failed to show up at a concert at her school in Bailey on Dec. 1. That is the day authorities say Maggie was murdered.

“Maggie was purposely set on fire and burned alive,” said Park County Sheriff Tom McGraw.

Law enforcement -- including agents from the FBI, ATF and Colorado Bureau of Investigation -- have conducted several searches in Maggie's home and have interviewed hundreds of people. A $50,000 reward has been offered in the case.

“Somebody knows what happened,” McGraw said. “Every tip will be addressed.”
