Police sources revealed today that in addition to the knife wounds to his abdomen and neck, Nicaraguan Diplomat Cesar Mercado had drain fluid in his system when he died. While the findings support the NYPD's theory that Mercado died of a suicide, they have yet to rule out homicide as the cause of death. Last night, friends and family gathered at the Ortiz Funeral Home in Washington Heights for Mercado's wake, and his sister told NY1 that they don't believe he would have taken his own life. "Until the authorities tell us otherwise we will continue to believe that there was a homicide in this case."
