Jeffrey Schlau pleaded guilty Tuesday to trying to kill his parents in their Depew home on Mother's Day after they refused to give him money for crack cocaine.
Schlau pleaded to second-degree attempted murder, second-degree assault and attempted reckless endangerment for stabbing his parents, Norbert, 54, and Joanne, 48, on May 12 in the family's home at 61 Marrano Drive.
Schlau, 21, also admitted trying to run over a Buffalo officer and ram three squad cars after police spotted him in his mother's stolen car and chased him down Hayes Place several hours after the knifings.
State Supreme Court Justice Christopher Burns had placed Schlau on probation March 13 on his guilty plea to robbing two gas stations and a liquor store in Depew and Cheektowaga in January to fuel his crack habit.
The judge Tuesday told him he is going to prison for 6 1/2 to 11 years for his latest crimes.
Burns, who ordered Schlau to remain jailed without bail pending his Dec. 2 sentencing, could have given Schlau a prison term of 8 1/3 to 25 years.
