Ex-NYPD officer charged with murdering beloved jogger, 28, was deemed so psychologically unfit he was thrown out of the Marines

The ex-NYPD officer now accused of murdering a jogger was once considered so psychologically unfit that the Marines expelled him from their ranks.

Sayed Mohassib, 27, allegedly fatally stabbed Katie Suarez, 28, on October 30 near Bay 17th Street and Shore Parkway in Bath Beach, New York.

Investigators initially explored a possible college link between him and the victim. Both attended Brooklyn College; however, the NYPD told the Daily Mail it doesn’t appear they are connected or knew each other.

Suarez, who was training for the New York City Marathon, was declared brain dead following the stabbing and remained on life support while doctors harvested her organs, according to the New York Post.

The 28-year-old donated her pancreas, liver, kidneys, and heart, saving five lives through organ donation this week.

Mohassib—who briefly served in the NYPD before being discharged from the Marines for psychological unfitness—was identified by police after video footage showed him leaving the Shore Parkway Greenway shortly after the attack.

After leaving the Marines, Mohassib tried to rejoin the police force but was denied and joined the Department of Education as a teacher’s aide at PS 200 in Bensonhurst.

The New York City Department of Education has since issued a statement confirming his suspension and that it will move to terminate his employment pending the outcome of the conviction.

He told officers at the 62nd precinct he had no recollection of the attack but woke up covered in blood with the murder weapon on him, the outlet reported.

Hours later, Mohassib emerged from the Bensonhurst police station in handcuffs, expressionless, as officers led him away around 4pm, where he was awaiting arraignment Saturday evening.

Prosecutors revealed during Mohassib’s arraignment that Suarez’s blood was found splattered on the walls of his Bensonhurst apartment, the New York Post reported.

‘The defendant stated that he had tried to clean the blood,’ Assistant District Attorney Jordan Rossman told the court.

Mohassib has since been arraigned on charges of second-degree murder, tampering with physical evidence and criminal possession of a weapon.

He was ordered held in custody and is due back in court on November 10.

Meanwhile, Suarez’s family, friends and community remain devastated by the loss.

Her mother—Yasira Suarez—confirmed her daughter had passed several days after the attack.

‘Destroyed. We’re all destroyed,’ she said, adding, ‘You took an angel.’

It was the young woman’s father who had gone out looking for her when he came across his critically injured daughter bleeding out in the nearby grassy area.

The bank teller was rushed to NYU Langone Hospital in critical condition, but the extent of her injuries became clear when she was declared brain dead.

Resident Anna Dece struggled to put her shock into words, saying the violence struck painfully close to home.

‘I’m very sad. That’s terrible. I’m sad for everybody,’ she said. ‘But this is close. It’s too much right now. It’s a mad world.’

The attack unfolded along the waterfront in Bath Beach, a residential corner of southern Brooklyn where locals use the shoreline paths for evening walks, cycling and exercise.

The stretch around Shore Parkway offers residents access to the waterfront overlooking Gravesend Bay and is part of the wider network of recreational routes running along Brooklyn’s coastline.

Suarez had been training for Sunday’s New York City Marathon when she was knifed and killed.
