Suzanne Morphew, mother who disappeared while riding a bicycle, died of homicide: Autopsy

Suzanne Morphew, the Colorado mother who disappeared while out on a bike ride in May 2020, died of homicide, according to an autopsy released Monday, the Colorado Bureau of Investigation said in a statement.

His death was determined to be caused by “homicide by undetermined means in the context of butorphanol, azaperone and medetomidine poisoning,” according to the autopsy.

“These drugs are marketed as a compound injectable chemical immobilizer for wildlife,” according to the El Paso County coroner’s autopsy.

According to the report, there were no signs of trauma to his body at the time of his death.

Barry Morphew, Suzanne’s husband, was charged with her murder in 2021, but the charges were dropped in April 2022, just before the trial began. No one has been arrested in the case since.

“The Colorado Bureau of Investigation and our law enforcement partners understand and appreciate the public interest surrounding this case,” CBI Director Chris Schaefer said in a statement Monday. “The investigative team assembled to work on this case continues to pursue the evidence and only the evidence as we seek justice for Suzanne’s death.”

His body was found in September 2023 while investigators searched an unrelated case. His remains were found in Moffat, Colorado, in Saguache County, about 90 minutes south of where he lived in Chaffee County.

“For the past four years, the Morphews have agonized over Suzanne’s disappearance,” the Morphew family said in a statement from their attorney. “This included not only the pain of losing their wife and mother, but also the false accusations and prosecution of Barry Morphew. The Morphews have prayed that authorities would take off their blinders and not only find Suzanne, but also find find the suspect responsible for her disappearance and murder, however, the Morphews are left with more questions than answers and a lack of justice for Suzanne, the family and the community.

In addition to his clothes, the autopsy indicates that a “spent bullet” was found next to his remains.

Barry and the couple’s adult daughters, Macy and Mallory, also accused investigators of not telling them whether they examined the bullet or the clothing for DNA evidence.

Barry and his daughters spoke to ABC News in May 2023 after filing a lawsuit against prosecutors saying they had wrongfully accused him.

“They have tunnel vision and they looked at one person and they have too much pride to say they’re wrong and look elsewhere,” Morphew said at the time. “I have nothing to worry about. I haven’t done anything wrong.”
