Rockland County prosecutors say that the teacher allegedly killed by her neighbor had walked in on him in her apartment. According to the Journal News, DA Thomas Zugibe said of defendant Eric Lau, "We know he killed [Jami Erlich] in the apartment. It appears she walked in on him inside the apartment while she talked on her cell phone." Erlich was on the phone with her boyfriend; because their conversation ended so quickly, the boyfriend tried to call her back without success and then called 911. Lau, whose past criminal history includes charges of forgery, impersonation, contempt and harassment and a jail sentence for attempted robbery, has pleaded not guilty; he was apprehended last week, apparently fleeing the police in the woods.
