Police: Man wanted ex to give him more time with son, then he killed them all
NEW YORK – On Monday, the friend who accompanied Linda Olthof from the Netherlands to New York couldn't get in touch with her and called Olthof's sister back home. Her sister Googled "New York" to see if anything was amiss there and quickly came across news of a murder-suicide. "She believed something had befallen her sister," NYPD Chief of Detectives Dermot Shea said Tuesday, per the Washington Post, and she was right: Olthof and her 6-year-old son, James, were dead, along with the new wife of her ex-husband, who was also dead.
