Katie Suarez, the 28-year-old jogger stabbed to death on a Brooklyn waterfront path, has saved the lives of four people through organ donation, the organ procurement organisation LiveOnNY has revealed.

Suarez, a registered organ donor, provided five organs to patients on the national transplant waiting list. Her heart, both kidneys, a liver and a pancreas were successfully transplanted into four recipients aged between 12 and 75. Three of the recipients live in New York and one lives in Florida. She also donated her corneas, giving another person the gift of sight.

"LiveOnNY is humbled and honored to be the stewards of these precious gifts of life so that Katie's legacy and others may live on," said Leonard Achan, the organisation's president and chief executive. "This is an unimaginable loss for any parent and family. That Katie thought of others in being a registered donor is a powerful testament to her generosity."

Suarez, a bank teller and graduate of Brooklyn College, was attacked at about 8pm on Friday 30 October while running east along the Shore Parkway Greenway in Bath Beach, near Bay 17th Street. She was stabbed in the neck and was on her way to meet her parents when the attack happened. Her father went looking for her when she failed to arrive and found her injured on the path.

She was taken to hospital, where she was declared brain dead, but was kept on life support so that her organs could be recovered for donation. Her family confirmed her death several days after the attack, and nearly 100 people gathered for a candlelight vigil in her memory on Wednesday 4 November.

Police arrested Sayed Mohassib, 27, at his home in Bensonhurst on Saturday 7 November. The former New York police officer, who now works as an elementary school paraprofessional, has been charged with second-degree murder, tampering with physical evidence and criminal possession of a weapon. On Sunday he pleaded not guilty in court and was remanded in custody without bail.

Investigators believe the attack was random. Police sources have said Mohassib told detectives he had gone to the Bath Beach promenade carrying a knife because he feared his family was being threatened, and that he woke from a blackout covered in blood with no memory of the stabbing. That account has not been tested in court, and no motive has been formally announced.

Earlier reports, citing police sources, had put the number of lives saved at five. LiveOnNY's statement, issued on Sunday, confirms four recipients received five organs, with the cornea donation restoring sight as well. Runners in the area have called for better safety measures along the Shore Parkway Greenway since the killing.
