NorthJersey.com Khalil Wheeler-Weaver displayed an unnerving lack of emotion when he exited an Essex County courtroom last December in handcuffs. Three years earlier, the Orange man killed his first victim at the start of a frenzied 88-day killing spree across North Jersey that ended only after the friends and family of one Montclair victim conceived a fake online profile to lure him to police. A two-month trial in the fall of 2019 presented more than 40 witnesses, Wheeler-Weaver's incriminating Google searches on how to make homemade poison and a videotaped police interview where he was caught in lie after lie about his exploits. Two hours was all a jury needed on Dec. 19, 2019 to convict him of killing three women — and attempting to murder a fourth — who narrowly escaped the same fate.
