People were told to avoid the area of Park Central Drive in Highlands Ranch as deputies investigated the homicide.

HIGHLANDS RANCH, Colo. — The Douglas County Sheriff's Office (DCSO) identified a woman found dead Saturday in her vehicle at the Central Park Shopping Complex and said they were investigating a related case of a man found dead elsewhere in Highlands Ranch.

The woman was identified as Jamie Sullivan, 49, of Highlands Ranch, according to the sheriff's office. 

The sheriff's office said it was investigating a related case of a man found dead in Highlands Ranch. He was identified as Art Valentine, 55.

Previously, DCSO had said Sullivan was shot to death and Valentine was dead of an apparent suicide.

The sheriff's office said the two knew each other and there was no threat to public safety.

In both cases, an autopsy has been performed. The results, along with the cause and manner of death, will be released when the investigation is completed, DCSO said.

Residents in Highlands Ranch were put under a precautionary lockdown Saturday when Sullivan was found shot to death in a vehicle in a parking lot. People were told to avoid the area of Park Central Drive.
