 Ikonomidis knocked on the door of neighbor Joy Liguori, who called the police. 
 
 “I saw the blood,” Ligouri told the Daily News. “It was out on the couch. That’s when I told him, ‘God, honey, you’re bleeding.’ He goes, ‘They stabbed me! They stabbed me twice! They stabbed me.” 
 
 Lynne Moeser, Ligouri’s relative, said Ikonomidis told her, “they hit me in the head, they hit my head with a bat.”
– Police arrested a suspect Monday in the murder of a 20-year-old man following a consensual threesome in New York City, the New York Post reports. Police say the victim, Manos Ikonomidis, had a threesome with an unnamed woman and a 21-year-old man. The woman got upset when one of the men tried to film their encounter and later told her boyfriend, 24-year-old Christopher Membreno, she had been raped. Police say she also sent a message to Ikonomidis' girlfriend telling her Ikonomidis "will be taken care of." Police say Membreno and two other men showed up at an apartment building early Monday, stabbed Ikonomidis multiple times, and hit him over the head with baseball bats. The New York Daily News reports Ikonomidis knocked on neighbors' doors asking for help while "gushing" blood. One building resident says it was like "something out of a horror movie." Police found Ikonomidis in the apartment building unconscious; he died at the hospital, according to Fox News. Membreno was arrested Monday evening. Police say they have no evidence the threesome wasn't consensual. A neighbor remembers Ikonomidis as someone who "always tried to help you out when you needed it."
