Sol Pais was already dead, from a self-inflicted gunshot wound, before the FBI and local authorities started a massive “manhunt” for her and hundreds of schools shut down along the Front Range.

The Clear Creek County coroner’s office on Wednesday released a statement saying that her death, near the base of Mount Evans, is “estimated to have occurred in the afternoon or early evening” of April 15, the same day she arrived in Colorado.

The coroner’s timeline is consistent with earlier findings of the Clear Creek County Sheriff’s Office, part of a team of law enforcement officers who found her body in a snowy, flat spot in the woods, off the path.

Authorities began a massive search for the 18-year-old April 16, the same day multiple schools went on heightened security. Late that night, school districts along the Front Range, including Denver, Jefferson County and Cherry Creek, canceled classes on April 17.

Pais’ body was found April 17 in a wooded area off the Rest House Trail near the Echo Lake Campground. She had no pulse.

“Autopsy revealed massive head injuries consistent with a self-inflicted gunshot wound, with no other injuries or marks present,” the coroner’s office said in a release Wednesday. The coroner’s office ruled her manner of death to be a suicide.
