ARAPAHOE COUNTY, Colo. -- The Arapahoe County Sheriff's Office is investigating the death of a 6-year-old after his body was found in an apartment when police responded to a call of a sexual assault Wednesday morning.
"It was heart-wrecking. Really sad," neighbor Selena Tzintzun said. "A 6-year-old lost his life today in a tragic way."
The sheriff's office responded to a call at 5 a.m. of a female who had been sexually assaulted at knifepoint by her male domestic partner, the sheriff's office said. The woman had fled the apartment and called 911 from a neighbor's residence.
"I just heard a lot of really hard door knocking," neighbor Maria Sanchez said.
"[Deputies] met with her, the apartment was quiet. Deputies didn't know if he'd left. I don't believe the female knew if he'd left," Arapahoe County Sheriff's Office spokeswoman Julie Brooks said. "So they didn't really know what they were working with except that, certainly it had involved a weapon."
When more deputies arrived and made entry into the apartment at 5:49 a.m., they found a 2-year-old boy unharmed in one bedroom. In another bedroom, deputies found an adult male suffering from what appeared to be self-inflicted knife wounds. They also found his 6-year-old boy deceased.
The adult male, adult female and the 2-year-old child were transported to the hospital. They have not been identified. Witnesses said the 6-year-old was not the female victim's child.
Deputies, rescue personnel and additional investigated the scene until 10 p.m. Wednesday.
A deputy responding to a call for additional units at the scene was involved in a crash around 6 a.m. and transported in critical, but stable condition to a hospital.
