Drugs found during the autopsy of Suzanne Morphew , the 49-year-old Colorado woman whose remains were found in September after she disappeared in May 2020, were consistent with a tranquilizing agent used to immobilize wildlife, according to a report released Monday by the Colorado Bureau of Investigation.

Morphews husband of 25 years, Barry Morphew, who was arrested in May 2021 on suspicion of first-degree murder in connection to her disappearance, previously told investigators who found a tranquilizer dart cap in the couples clothes dryer that he tranquilized deer bucks to cut off their horns . Charges were dropped before he went to trial in 2022, according to The Associated Press .

Morphews death was ruled a homicide by undetermined means in the setting of butorphanol, azaperone, and medetomidine intoxication, according to the autopsy report.
