A former NYPD officer who most recently worked as a teacher's aide in city schools has been charged with second-degree murder in the death of Katie Suarez, the 28-year-old jogger stabbed on a Brooklyn waterfront path on Oct. 30.

Sayed Mohassib, 27, was arrested Saturday. He also faces charges of tampering with physical evidence and criminal possession of a weapon, CBS News New York reported.

Suarez was running on the Shore Parkway Greenway in Bath Beach at about 8 p.m. when she was stabbed in the neck. She had been on the phone with her parents. The call cut off. They went looking for her, Fox News reported, and her father found her bleeding in the grass near the path. She died at NYU Langone Hospital-Brooklyn.

According to 6abc, police said Mohassib told detectives he had no memory of the killing but did recall being covered in blood.

Surveillance cameras near the path helped investigators find him. ABC7 New York reported that detectives also pulled video from the Caesar's Bay Shopping Center, where Suarez worked at a bank.

When Mohassib appeared in Brooklyn Criminal Court on Saturday, prosecutors said Suarez's blood was found on the walls of his apartment, Newsweek reported, citing The New York Post.

Police have found one link between the two: both attended Brooklyn College at the same time. Police sources told CBS News New York there is no evidence they knew each other.

City employment records show Mohassib joined the NYPD in 2022 and resigned that December, according to Newsweek. Police said he left to join the Marines and later tried to get back on the force.

Investigators have not given a motive.
