About John Agrue
John William Agrue (September 11, 1947 – June 29, 2009) was an American murderer who was posthumously identified as a serial killer. He was convicted in 1966 of murdering his 15-year-old sister-in-law in Joliet, Illinois, and was later linked to a 1982 killing in Longmont, Colorado, after his parole from prison. He was arrested that year for an attempted kidnapping but was not charged in the Colorado homicide at the time due to a lack of evidence. After his death in 2009, DNA evidence identified Agrue as the killer of 94-year-old Orma B. Smith, and authorities later named him the primary suspect in the stabbing death of Susan Becker. Based on these findings, investigators stated that he was responsible for multiple killings and reexamined other cases for possible links. == Murder of Susan Marino == On July 21, 1966, an 18-year-old Agrue met with his 15-year-old sister-in-law Suzanne "Susan" Marino in downtown Joliet, Illinois and asked her to accompany him to Hammel Woods forest preserve. When they arrived there, he started making romantic advances towards her, but she rejected him. Angered, Agrue pulled out a small knife and stabbed her approximately a dozen times, killing her. Later that day, he admitted the murder to his wife, who initially did not believe his claims. To prove his guilt, he drove her to the crime scene and showed her where he had left Marino's purse and shoes.
