Police: Person of interest now a suspect in Buffalo Grove stabbings

A Buffalo Grove man stabbed as he fought off intruders at his home just after midnight Wednesday remains hospitalized with injuries that are not life-threatening, Buffalo Grove police said Thursday.

Officials have not yet released a suspected motive behind the break-in on the 400 block of St. Mary's Parkway that left the homeowner and three others, as well as the family dog, with stab wounds.

Buffalo Grove Police Department Public Information Officer Meghan Hansen said the department is pursuing "several leads" on why the stabbing happened, and investigators are working on the case "pretty much around the clock."

Two of three people investigators questioned as persons of interest Wednesday have been released, but the third remains in custody. Authorities are not releasing the person's name because charges have not been filed.

In the meantime, a GoFundMe page has been set up at to help the family pay the veterinary bills for their German shepherd, Piston. He underwent surgery for treatment of a shoulder injury suffered during the home invasion, officials say.

"The family would appreciate their privacy be respected during this difficult time," said Amanda Busch, a friend of the family who set up the GoFundMe page. "Piston is out of surgery and currently in stable condition. We appreciate the community support."

According to the page, Piston's bills eventually could exceed $6,000. The page had raised more than $3,700 as of Thursday afternoon.

Police said they believe the home invasion and subsequent attack were not random and there is no further threat to the community.

Officers responded to the home at 12:06 a.m. Wednesday, after a 911 caller reported two masked men with a large hunting knife had broken in and repeatedly stabbed the 47-year-old homeowner.

The homeowner was able to retrieve and fire a handgun during the attack, forcing the intruders to flee, according to police.

The three other people who suffered stab wounds were taken to an area hospital where they were treated and released Wednesday, police said.

A fifth person who was in the house at the time of the stabbing, was not injured.

Sgt. Michelle Kondrat said three of the people inside the house were related and the two others were friends who did not live at the home.
