Investigators believe a 24-year-old fatally stabbed his girlfriend and her two young daughters in a Flatbush residence, then told a relative he had committed the crime. After getting a tip from the relative, police arrived at the home on Rogers Avenue at around 1 pm today and the suspect — identified as Jermaine Ruiz — reportedly opened the door in clothing "splattered in blood." The Times reports that when officers from the 67th Precinct entered the home they found the bodies of Rogers' 22-year-old partner, as well as her daughters, ages 2 and 5. According to 1010WINS, the bodies were found in the kitchen. Law enforcement sources said the suspect might have been putting the children into plastic garbage bags, and noted: "We think they have been dead for a couple of days."
