Buffalo Grove police continue to investigate the motive behind an early morning home invasion Wednesday that left four residents and their dog recovering from stab wounds.

No charges have been announced from the attack inside a single-family the home on the 400 block of St. Mary's Parkway. Sgt. Michelle Kondrat said at about 8:45 p.m. that two of three "persons of interest" questioned earlier in the day were allowed to leave, while the third person, who has not been identified, remains in police custody.

 

Officers responding to a 911 call from the home at 12:06 a.m. Wednesday were told that two masked men with a large hunting knife broke in and repeatedly stabbed the 47-year-old homeowner, authorities said.

During the attack, the homeowner was able to retrieve and fire a handgun, forcing the intruders to run away, according to police.

The 47-year-old homeowner was in serious condition at a hospital Wednesday, police said. The three others were treated and released. All the victims are between the ages of 16 and 47, police said.

Kondrat said there were five people in the home at the time of the robbery. She said three of the people inside the house were related and the two others were friends who did not live at the home.

The dog, a German shepherd, was brought to an emergency veterinary clinic by an officer. Its condition is unknown.

Police did not offer a possible motive for the attack.

A man identifying himself as the uncle of the home's owner declined to comment on the attack while leaving the residence Wednesday afternoon but said all the victims were recovering.

After arriving at the scene early Wednesday, Buffalo Grove police sent descriptions of the attackers to area police departments. Two men matching those descriptions later were detained by Wheeling police at Lake-Cook and Weiland roads, officials said.

Evidence of their involvement in the home invasion, including a bloodstained hunting knife believed used in the attack, was recovered, police said.

Buffalo Grove police say they are confident there is no further threat to the community.

Nataliya Plotnikova, who lives next door to the home where the attacks took place, said she noticed nothing unusual at her neighbor's home when she was out walking her dogs at 11:45 p.m. Tuesday. The first sign of trouble was when emergency vehicles began arriving a short time later.

                                                                                                                                                                                                                       
 

"We were scared," she said.

Plotnikova said a man and his children who appear to be in their teens live in the home.

Rachael Link, who lives two houses away, said she was feeding her newborn when a fire truck, ambulances and police cars rolled up on her block at 12:09 a.m.

Link, who was outside with two children and neighbors Wednesday morning, saw emergency crews wheel a young man out of the house on a stretcher.

"This was quite unusual for the neighborhood," she said.

Another neighbor walking her dog Wednesday morning said she did not know the residents of the home but described the neighborhood as typically quiet.

"I'm thoroughly disgusted with the whole situation," Gayle Bonea said.
