Teacher's aide accused of stabbing jogger fled home in underwear, records show

Court documents released this week detail the actions of Sayed Mohassib, a 27-year-old teacher's aide accused of fatally stabbing a jogger in Bath Beach.

Surveillance footage captures Mohassib walking onto the bike path along the Belt Parkway shortly before the Oct. 30 attack. Minutes later, Katie Suarez was stabbed twice in the neck while running the path. She had called her father at 7:56 p.m. to let him know she was out.

After the incident, video shows Mohassib leaving the scene and returning to his home. He told detectives that he felt compelled to walk to the area with a knife or his family would be killed. He claimed he woke up covered in blood but did not remember stabbing anyone. He said he rushed home to discard the knife and his clothes, but blood spilled across his apartment, forcing him to scrub the mess. Security cameras recorded him exiting his residence in only his underwear and tossing items into a garbage chute.

When investigators entered his second-floor apartment, they found a reddish stain on the wall. Tests confirmed the substance was blood. Mohassib was arrested over the weekend and charged with second-degree murder and criminal possession of a weapon.

Mohassib worked as a teacher's aide at P.S. 200 The Benson School. Sources indicated he returned to the classroom after the murder. He previously spent a month in the NYPD field training unit in the fall of 2022 before leaving. He was also discharged from the Marines after failing a psychological evaluation.

Suarez' father grew concerned when she did not return from her run on Oct. 30. He found her injured under a tree that night. NYPD Chief of Detectives Joseph Kenny stated that a heavy blood trail, described as arterial spurting, was visible at the location. He noted that Suarez ran approximately 150 feet before collapsing. Kenny said the wounds were from an upward trajectory through her neck that hit a vein and entered her oral cavity.

Suarez remained on life support for several days before dying the following week. The city's medical examiner ruled her death a homicide on Nov. 6, one day before Mohassib was arrested.
