Chilling new details about missing Colorado mom Suzanne Morphew’s possible last moments emerged in court last week when prosecutors began laying the groundwork for their murder case against her husband.

Suzanne, 49, was reported missing after going on a Mother’s Day bike ride on May 10, 2020. She is presumed dead. Her body has not been found.

Her husband, Barry Morphew, 53, is charged with first-degree murder after deliberation, tampering with physical evidence and attempt to influence a public servant. He has not entered a plea and remains in the Chaffee County Detention Center.

On Tuesday, the second day of a four-day preliminary hearing to determine whether Barry will stand trial for allegedly killing Suzanne, now-retired FBI Agent John Grusing testified that investigators found a tranquilizer cap in the dryer of the Salida home where the couple lived with their daughters,CBS Denver,9 NewsandKDVRreport.
