At a court hearing just hours before he would stab to death his mother, wife and two daughters inside their Buffalo Grove home, Andrei Kisliak was unusually calm, friends of his wife told police.
Authorities believe that Kisliak, 39, carried out the killings with a large knife they found “protruding from his chest,” and autopsies by the Lake County coroner’s office showed “sharp force injuries” caused the deaths of Vera, 36, Vivian, 7, Amilia, 4, and Lilia Kisliak, 67.
A series of 911 calls made by Vera and Andrei Kisliak were released Friday, shedding more light on how problems in their estranged marriage escalated in the months leading up to Andrei s murdering his wife, mother and two young daughters in their Buffalo Grove home.
