SHERMAN OAKS – Forensic experts went to the Sherman Oaks home where a woman was beaten and stabbed to death 22 years ago to test a claim made by her son, who was convicted of the murder. State attorneys joined in the four-hour examination of the home where Dorka Lisker was attacked in 1983. Her son, Bruce Lisker, was convicted of first-degree murder in 1985 and is serving a life sentence. Attorneys for Lisker, 40, will argue at a federal court hearing in December that he was unjustly convicted and the case should be re-examined. The day of the killing, Lisker told police he returned home to find his mother near death. Lisker said he looked through a window at the back of the house and saw her lying on the floor after she was attacked by an unknown intruder.

But after visiting the home in March, retired prosecutor Phillip H. Rabichow said that argument might have been wrong. The family that now owns the home permitted crime scene experts for both the defense and the prosecution to examine the home Saturday and make measurements. “There’s no doubt that he could have seen his mother, even from where the prosecution says she laid,” said William Genego, an attorney for Lisker who was present. Deputy Attorney General John Yang, who is defending Lisker’s conviction, declined comment.
