Sidney Reso was abducted from his Morris Township, New Jersey, home on this day. He was killed almost instantly, but his kidnappers carried through their ransom demands.

The main demand was for $18.5million in used $100 bills, and the notes were sometimes signed 'Rainbow Warriors' an apparent link to the environmental group.

However, police collected DNA from the ransom notes and the public phones used to issue their demands and a disaffected employee of Exxon, Arthur Seale was traced.

Seale had been a police officer, and also served as an Exxon security consultant but he had been fired in 1987. The motivation for the crime, however, appears to have been mainly greed - the couple had debts.

Arthur and his wife, Irene, were both arrested on June 19, 1992.

Irene was persuaded to testify against her husband, and led the authorities to Reso's body.

Arthur was convicted and sentenced to 95 years in prison and fined $1.75 million. Irene Seale received a 20-year sentence.
