The pair was standing near the shallow end of a pool in the back yard of one of Long Island’s most exclusive neighbourhoods on Wednesday morning. Authorities said Denis D. Cullen Jr. was refusing to take his medication and his mother, Elizabeth Cullen, was scolding the 23-year-old, according to Newsday. At some point, Cullen would later tell police, he decided he had had enough. “The argument escalated to the point where she had poked him,” Assistant District Attorney Robert Biancavilla told reporters, according to Newsday. Cullen told police that he met up with one of his sisters and confessed to the crime, which led family members to call police, the paper reported.
