Police say a Colorado teenager went on a stabbing spree, allegedly killing his mother and seriously injuring his sister. The Douglas County Sheriff’s Office arrested 18-year-old Messiah Williams on July 20, 2025, a short time after his unidentified sister called 911 for help. He faces multiple charges and life in prison if convicted.
According to a release from the Douglas County Sheriff’s Office, deputies responded to a call about a stabbing at an apartment in the 1300 block of Sweet River Circle about 11:30 p.m. Deputies forced their way into the Castle Pines apartment and found Williams’ unidentified mother deceased. They began life-saving measures on his sister, including putting a tourniquet on her arm, before taking her to a hospital.
Deputies tracked down Williams a short time later and took him into custody without incident. According to an arrest affidavit obtained by KRDO, deputies found Williams naked near the apartment. A witness told police they saw him discarding something in a nearby dumpster. Investigators believe he put his clothes inside.
Court documents revealed Williams did not live at the apartment with his mother and sister. He allegedly began staying there just two days prior after he was kicked out of an addiction treatment facility, per KRDO. His sister told police everything seemed normal the night of the stabbing until she heard her mother scream. When she tried to help, Williams allegedly attacked her.
During a news conference, Douglas County Sheriff Darren Weekly thanked deputies for acting quickly and apprehending the suspect.
“I can’t praise their response enough for how quickly they got here, how quickly they made the decision to force entry – not only on the exterior door, but also on the interior door – it saved a life,” he said. “I’ve been here for 32 years and I cannot remember the last time we had a homicide in Castle Pines.”
Williams faces multiple charges, including murder in the first degree, attempted murder in the first degree, assault in the first degree, and tampering with physical evidence.
Per Colorado law, he could face life in prison without parole if he’s convicted.
