BUFFALO GROVE, Ill. (WLS) -- Police in Buffalo Grove continue to investigate after five people were found dead in a home Wednesday, including two children.
Lake County Coroner Jennifer Banek identified the victims as Lilia Kisliak, 67; Andrei Kisliak, 39; Vera Kisliak, 36; Vivian Kisliak, 6; and Amilia Kisliak, 4.
Banek said autopsies show the cause of death was due to sharp force injuries for all five victims.

Police said around 11 a.m. Wednesday, officers went to a two-story home in the 2800-block of Acadia Terrace after receiving a call for a well-being check for a woman made by her co-worker.
After no one came to the door, police said they made forced entry and found five people dead inside.
Lake County court records show multiple filings by the Kisliaks, including a divorce petition and an order of protection filed by Vera against her husband Andrei in which she alleges he had a history of violence and a history of possessing or using firearms.
The weapon was later turned over to police.
"She confided in my mom, and my mom told her, 'You need to get out," said family friend Liliya Dzhorayeva.
In the affidavit, Vera said her husband had threatened to kill and disfigure her, and at one point had hidden away the children.
Records show that Andrei was arrested in September for violating the protection order when he allegedly entered the home while his wife was there. He was freed after posting 10% of a $5,000 bond.
Neighbors said Vera spoke to them about the family's troubles.
"It seems like the system failed her somehow, because I know she was in court," said Baron Harmon, neighbor. "I know she had filed protection orders."
Harmon has lived in this area for 40 years and stopped to bring flowers to place outside the home. He fondly remembered seeing the children outside every morning.
"I knew there was something up when I didn't see them out in the morning and I thought well, you know, maybe I thought it was colder, they got a ride to school or something," Harmon said. "It's really sad."
Neighbors said many have never seen anything like this before.
"Eighteen years, my kids grew up here... you never see it, never seen anything like this ever," Buffalo Grove resident Falguni Patel.
"It's a shock," resident Michelle said. "Good area, quiet area. Everyone kind of keeps to themselves, but everyone still knows each other, so it's just sad. "
Police said their investigation is ongoing, but did confirm the deaths were the result of a domestic-related incident and that there's no active search for any suspect and no danger to the public.
"Our sincerest and heartfelt condolences go out to the families of the victims of this tragic incident," Buffalo Grove Police Chief Brian Budds said. "Today is a very sad day for our community as we continue to process this unthinkable event."
"It's really sad," Harmon said. "It was hard to sleep last night. It's a shame that you say to yourself, 'Did I miss something? Should I have spotted something?'"
The Lake County Major Crimes Task Force is assisting in the investigation.
