According to a statement from the Arapahoe County Sheriff’s Office, deputies received a report around 5 a.m. of a woman who was sexually assaulted at knifepoint by her partner at an apartment complex near East Yale Avenue and South Quebec Street.

The woman had fled her apartment in the 7500 block of East Harvard Avenue and called 911 from a neighbor’s home, the statement said.

Deputies arrived about five minutes later, spoke to the woman and then searched the apartment where the sex assault happened around 5:50 a.m.

The apartment was quiet when deputies entered and they were unsure if the suspect was still there. Inside, deputies found 2-year-old boy unharmed in a bedroom. In another bedroom, they found a man suffering from what appeared to be self-inflicted knife wounds, the statement said, and a 6-year-old boy who was deceased.

The statement didn’t say how the boy died, but said deputies are investigating his death as a homicide.

The man, woman and 2-year-old boy were all taken to the hospital. ‘

No names have been released.

Only a handful of police vehicles remained at the scene around 9 a.m. Wednesday.

An Arapahoe County sheriff’s deputy responding to the scene around 6 a.m. was injured when he crashed his cruiser near East Iliff Avenue and South Valencia Street. The deputy, who has been with the sheriff’s office since 1990, is in critical but stable condition.

The deputy’s mangled cruiser, along with a red Ford pickup truck, remained at the scene around 9 a.m. Wednesday. Investigators from the sheriff’s office and the Colorado State patrol, which is leading the crash investigation, were also on scene.

In a statement Wednesday morning the State Patrol said the police cruiser was following an ambulance west on Iliff when a Ford F-350 tried to turn left from eastbound Iliff to northbound Valencia Street in front of the police cruiser. The truck slammed into the police car, causing it to spin and come to a stop on the northside of Iliff.

Both the ambulance and police car had their lights and sirens on at the time of the crash.

The driver of the Ford, Felipe Castanda Alacala, 58, was unhurt in the crash, CSP said.

The deputy was rushed to Medical Center of Aurora.
