Aurora man faces 96 years in prison after murder verdict

Shane Dorsey, 52, was convicted of second-degree murder in the death of his wife, Lisa Marino-Dorsey, 57. The Arapahoe County jury reached its verdict after a seven-day trial. If the court upholds three habitual criminal sentence enhancements, Dorsey faces a mandatory 96-year prison term.

Marino-Dorsey was last seen by anyone other than her husband on Dec. 28, 2021, at the couple’s home in Aurora. According to prosecutors, she stopped answering calls and messages from family and friends that day. Her personal belongings, including her clothing, suitcase, cellphone, and dog, remained at the residence.

Police records show a history of domestic violence between the couple dating back to 2013. Aurora police documented dozens of calls for service involving physical assault, strangulation, and threats. On Dec. 25, 2021, Lisa reported that her husband struck her in the head three times with a bottle during an argument. Responding officers observed a lump the size of a golf ball on her head.

Two days later, a dispute at the home involved damage to a roommate’s car. Lisa sent the roommate messages describing physical abuse by her husband. Her brother requested a welfare check on Jan. 2, 2022, after several days without contact. Officers found no one at the home, and her brother reported her missing to police on Jan. 3, 2022.

Initially, Dorsey told others that his wife had left after an argument with a roommate and might have gone to New York to visit family. Investigators determined she did not travel to New York. On Jan. 5, 2022, the Colorado State Patrol found Lisa’s car on Interstate 25 near RidgeGate Parkway, south of Lone Tree. The vehicle had extensive damage, and footprints led away from the scene. Her personal belongings were found inside the car.

Digital evidence placed Dorsey’s phone in Colorado Springs between Jan. 4 and Jan. 5, 2022. Detectives identified activity involving Lisa’s car in Colorado Springs before the interstate crash. Authorities never found Lisa’s body, and the case went cold for several years. Eric Ross, spokesperson for the 18th Judicial District, stated the conviction followed years of investigative work.

The Aurora Police Department reopened the investigation on Nov. 15, 2024. Detectives conducted additional interviews, reviewed historical digital evidence, and pursued new leads. They spoke with witnesses who had not previously told investigators their accounts.

Senior Chief Deputy District Attorney Michael Mauro said the absence of remains presented a challenge for prosecutors. “But the absence of a body does not mean the absence of evidence,” Mauro said in a statement. Prosecutors presented evidence that Lisa’s regular spending and medical appointments stopped abruptly after her disappearance. There were no additional bank transactions or communications from her. “The evidence established that Lisa was no longer alive,” Mauro said.

Senior Deputy District Attorney Lauren Crisera said the conviction could not erase the loss experienced by Lisa’s family. She hoped the verdict would provide the family with comfort and recognition that Lisa had not been forgotten. Dorsey is currently held in the Arapahoe County Jail without bond. Sentencing is scheduled for Feb. 4, 2027.
