Fort Collins police are seeking more information and witnesses in an attempted murder case, in which a Fort Collins man has been targeted twice.

John Henson was first targeted in this case on May 15 at approximately 9 p.m. when a person driving a green four-door sedan purposely struck Henson, according to a May 18 press release published by Fort Collins Police Services.

Henson was crossing Linden Street near the Poudre River Bridge during this first incident. He sustained minor injuries and police believe the vehicle that struck Henson was located on May 16.

A man allegedly attempted to slash Henson just one day after the first incident occurred.

On May 16 at approximately 2:20 p.m., police received a disturbance call at the Catholic Charities mission after 24-year-old Brenton Dolph allegedly attempted to slash Henson.

Henson did not sustain any injuries, and Dolph was arrested without incident nearby.

Dloph faces charges of aggravated intimidation of a victim (a class three felony) and attempted first degree assault (a class four felony). Additional charges are pending.

Detectives believe these incidents are related and that more people may have witnessed them taking place.

Anyone who has any information regarding these incidents has been asked to contact Detective Jason Curtis at (970) 221-6560, or contact Crime Stoppers of Larimer County at (970) 221-6868 or www.stopcriminals.org. Callers may remain anonymous.
