Over 2,000 people have signed a petition appealing to the U.S. Attorney in the District of Colorado to bring more charges in the case of Kelsey Berreth’s presumed murder.

Berreth’s fiance Patrick Frazee, the father of her toddler daughter, is awaiting trial on murder charges. Krystal Lee Kenney, a nurse in Idaho who had been romantically linked to Frazee, pleaded guilty to one count of tampering with evidence and provided testimony to investigators detailing months leading up to Berreth’s presumed murder at Frazee’s hand, following multiple attempts to solicit Kenney to commit the crime. Kenney also admitted to driving to Colorado on Thanksgiving weekend to clean up the bloody crime scene, at Frazee’s behest.

As reported by KOAA, a Change.org petition addressed to U.S. Attorney Jason R. Dunn and Katherine Sullivan, Acting Director Federal Office of Violence Against Women, requesting that Kenney and unnamed “co-conspirators” be charged with conspiracy to commit murder.

“…  Krystal Lee Kenney, has specifically identified the individuals, as those who voluntarily took overt actions to discuss, plan, conceal, supply and otherwise facilitate her efforts to murder Kelsey Berreth,” the petition reads.

Kenney’s apparently outsized role in the concealment of the murder has raised concerns about the plea agreement she made with Teller County prosecutors, which carries a maximum sentence of three years and no minimum sentence.

On Wednesday, Woodland Park police announced that a landfill search for Berreth’s remains did not produce a body or any evidence connected to the homicide investigation.
