Farrell’s stepfather declined to comment afterward. The couple also have five other children.Prosecutors accused Farrell of “intentionally” striking his mother several times with an ax at their Norway Pine Drive home last month, according to court documents.Both prosecutors and Russo said Farrell admitted himself into Bellvue Hospital after the incident, though they did not say when or how long he was hospitalized.Farrell has no criminal record.Pearl told the judge that Farrell gave an admission to a family member after the alleged murder. Russo argued that the statements were “based on hearsay” and that authorities have not provided any evidence linking his client to the crime.The alleged admission was based on a Dec. 15 phone call to his 69-year-old grandmother that Farrell made from the hospital, according to the grandmother’s sworn statement to police.“He told me he killed his mom, my daughter and that he was selfish and should have killed himself,” Farrell’s grandmother told a Suffolk County police detective inside his parked car one day after the phone call.“Sean told me he was scared and confused,” she said, according to court documents. “He was crying and I told him to talk to his doctors who would help him.”The grandmother told police that her caller ID said the incoming call was placed from Bellevue Hospital. He also inquired about how his two brothers were handling their mother’s death, according to the sworn statement.“He was saying other things but he was crying and I could not understand him,” she said. “I began crying also and we hung up.”Russo characterized Farrell as “calm, scared” before the arraignment. He told reporters that he did not have information regarding Farrell’s relationship with his late mother.
