John W. Yengo, a former Jersey City Municipal Court judge, was 72 when he was admitted to St. Barnabas Hospital in Livingston, New Jersey, in 1988 for what was first thought to be a severe sunburn but later understood to be an allergic reaction to a heart medication.

Yengo’s death was not initially treated as a homicide. It was later reclassified after Cullen was identified as a serial killer; he ultimately confessed to Yengo’s murder along with numerous other patient deaths. The admission for a seemingly manageable condition and the fact the lethal act occurred under the cover of medical care are central to this case.

Did anyone who knew Judge Yengo or worked at St. Barnabas in 1988 notice anything unusual about his stay or treatment?
