Ricky Lee Green (December 27, 1960 – October 8, 1997) was an American serial killer who murdered at least four people in Texas between 1985 and 1986, at least two of which were killed with the help of his wife, Sharon.

Together with his siblings, he was physically abused by his father on an almost daily basis, with the elder Green applying electro shocks to their bodies, punching them in the stomachs or holding them underwater until they nearly drowned when they went on fishing trips.

[7] Green's final known killing occurred on December 29, 1986, when he picked up an acquaintance, 28-year-old KXAS-TV sales executive Steven M. Fefferman, at the beach, as the former wanted to celebrate his birthday by having casual sex.

[3] Over the next two years, Sharon divorced her husband and went to a drug addiction counsellor in Stephenville, to whom she eventually confessed that her ex-husband had killed multiple people.

[9] While held in the Tarrant County jail on $1.25 million bond, Green confessed to the four murders and was questioned in eight similar killings that had occurred in the Fort Worth area.

[9] During the investigation, authorities were told by Sharon and Bill Green about a mysterious mattress, allegedly covered in a potential fifth victim's blood, which Ricky had given to his father for storage.

[11] In February 1990, Sharon Green was found guilty in the Monroe and Bailey murders, but, as part of a plea bargain, she was sentenced to 10 years probation.

[18] In a break of procedure, prison officials had to use only a single needle instead of the customary two, as they had trouble finding a suitable vein to inject due to Green's long-time drug addiction.
