A man’s body was found in the trunk of a car at a Fourmile Canyon home on Tuesday, and one person has been arrested on suspicion of murder in relation to the death.

Stephen Christopher Wolf, 25, of Gold Hill, was arrested on suspicion of first-degree murder, felony murder, second-degree burglary, tampering with a deceased human body and tampering with physical evidence.

According to an arrest affidavit, Jeffrey Michael Lynch, 57, was reported missing Tuesday by his son after Lynch failed to show up to his girlfriend’s house on Sunday.

Lynch had been working on a vacant house on Camino Bosque in Fourmile Canyon, so the property owners went to see if Lynch was there. The owners arrived and found Wolf, who they did not know, sitting in Lynch’s car in the garage.

The property owner confronted Wolf, who said he was there to clean before saying the police were after him. The homeowner said she had not hired anyone to work on the house other than Lynch, and called the Boulder County Sheriff’s Office.

When deputies arrived, they found Wolf carrying a handful of shovels in a trash bag, according to the affidavit. Wolf saw the deputies and ran into the garage, but the two deputies were able to handcuff him.

One of the deputies was familiar with Wolf because of past contacts with him and knew him as a sovereign citizen. The doctrine of the sovereign citizen’s movement holds that people are only answerable to common law and that the U.S government is illegitimate. The FBI has said that the more extreme sovereign citizens are “domestic terrorists” and labeled them a “growing threat.”

Wolf told the deputies, “I want my lawyer,” and “I’m going to claim insanity.”

Deputies searched Lynch’s car and found a body wrapped in plastic in the trunk of the vehicle. The deputies noted there was an odor of decomposition, indicating the body had been there for some time.

Deputies also noticed Lynch’s driver seat had been wrapped in plastic and smelled a strong odor of bleach in the garage.

The Boulder County Coroner’s Office confirmed Wednesday night the body found in the trunk was Lynch.

While a possible cause of death was not listed in the affidavit, deputies found a blood-stained knife on Wolf as well as a loaded handgun in the garage.

While in police custody, Wolf made several spontaneous utterances about being set up and the garage “magically opening” and said that Lynch attacked him.

According to the affidavit, Wolf’s family said he has been diagnosed as paranoid schizophrenic and was recently cut off financially until he agreed to get mental health treatment. Wolf’s brother in Illinois said Wolf called him early Tuesday morning sounding “panicked” and talked about coming back to Illinois.

Wolf had been arrested three times in 2018 for obstruction, for having a loaded weapon in a vehicle and for failure to comply. His car was also possibly involved in a hit-and-run in Boulder and a vehicular eluding at the University of Colorado Boulder on Sunday.

Officials are not releasing Wolf’s booking photo because of the ongoing investigation. He is being held without bond at the Boulder County Jail as he awaits a hearing on Friday morning.
