Sayed Mohassib, a 27-year-old former NYPD officer who worked as a city public school aide, was charged Saturday with second-degree murder in the fatal stabbing of Katie Suarez, a 28-year-old bank teller attacked while jogging along the Shore Parkway Greenway in Bath Beach, Brooklyn, on October 30.

Mohassib was also charged with tampering with physical evidence and criminal possession of a weapon, police said. He was arraigned Saturday evening in Brooklyn Criminal Court and held without bail by Judge John McPadden. His next court date is November 10.

At the arraignment, Assistant District Attorney Jordan Rossman said Suarez’s blood was found splattered on the walls of Mohassib’s Bensonhurst apartment, and that the defendant had tried to scrub it away before police arrived. “The defendant stated that he had tried to clean the blood,” Rossman said. The prosecutor said Mohassib “made admissions and there are video recordings to support the case.” Prosecutors gave no motive. Mohassib said nothing during the hearing except to correct the judge’s pronunciation of his name. His attorney, Edward Mandery, asked that Mohassib be placed in protective custody and said a psychiatric evaluation was not needed “at this time.” “I just want to make sure my client doesn’t get hurt,” Mandery told the New York Post, adding, “there has been a lot of media attention on this case.”
