Tragedy struck a quiet neighborhood in Wheeling, Illinois, where a couple entangled in a "strained domestic relationship" were found dead in their home. The Wheeling police, responding to a 911 call around 5:42 p.m. Thursday, discovered the bodies of Marisa Dister, 46, and Russell O'Connor, 44, on the 300 block of West 12th Street, the Chicago Sun-Times reports. A gun was found near their bodies, prompting a police investigation that has indicated no current threat to the public.

According to ABC7 Chicago, neighbors were left reeling from the incident, expressing shock and mourning the loss of what they remembered as "very nice people." "We were like scared, what happened here?" a local resident, Nikita Shah, told ABC7 Chicago. The large police presence on Thursday night, with "like seven or eight cars here, lot of people," was a stark contrast to the normally peaceful cul-de-sac.

Previous incidents had led to prior police involvement at the home, one neighbor, choosing to remain anonymous, revealed in an interview obtained by ABC7 Chicago. Recalling friendlier times, the neighbor shared, "I'm shocked, you know? Two months ago he was cleaning our driveway...I'm sad because they were very nice people. They were nice to us." Further chilling details emerged as court documents showed that O'Connor had once sought an emergency order of protection against Dister, although it expired in the summer of 2016.

An autopsy was scheduled to provide more answers about the circumstances that led up to the couple's death. As the community grapples with the sudden violence, authorities continue their investigation, assuring the residents that the tragedy seems contained, with no broader threats looming. Full details on the deaths have not yet been released, but the grim discovery has certainly left its mark on a shaken community.
