The Nurse (New Jersey 90's)

n the 1990s, a nurse in New Jersey killed hundreds of hospital patients.

Sometimes he would sneak into patient's rooms at night and inject them with fatal medication doses. Other times, he would put the medication into IV bags in the supply room, so they would kill whatever random patient they were given to later.

He was accused several times. Some patients pointed him out before they died. Some staff thought he was creepy and dangerous, and refused to work with him. He kept getting fired from hospitals. But the hospital managers knew that if he got arrested, they would be sued by the families of the patients he murdered. So they just fired him, and didn't call the police.

That happened at 12 different hospitals over the course of 16 years. Investigators believe he killed as many as 400 people.

After he was arrested, he confessed to 40 murders. In 29 of them he gave enough detail to be charged and plead guilty. He is linked to 300+ more deaths than that, but details of those will probably never be known, because so much information was lost over time or destroyed by the hospitals.
