Modus Operandi - Stabbing

Mark Howard Wilson Jr. was convicted of murdering brothers Robert Baker, 12, and Tayten Baker, 14, in Melrose, Florida, on August 26, 2020. Wilson was the boyfriend of the boys' aunt, Cynthia Guinan, and had moved with her and their young daughter into a shed on the Baker family's property only five days before the killings. Robert and Tayten were found beaten with a hammer and had their throats cut. Wilson was convicted of two counts of first-degree murder, burglary with assault or battery and armed burglary. A jury unanimously recommended death, and in January 2023 a judge sentenced him to death for both murders. The Florida Supreme Court affirmed his convictions and sentences in May 2025.

Alexander Christopher Ewing was responsible for four murders during a series of violent attacks in the Denver metropolitan area in January 1984. On January 10, he sexually assaulted and murdered 50-year-old Patricia Louise Smith in her Lakewood home, and six days later attacked the Bennett family in Aurora, killing Bruce Bennett, his wife Debra and their seven-year-old daughter Melissa with a hammer. The crimes remained unsolved for more than three decades until DNA evidence linked Ewing, who was already serving a prison sentence in Nevada, to the killings. He was convicted of the three Bennett murders in 2021 and Patricia Smith's murder in 2022, receiving three consecutive life sentences for the Bennett killings and another life sentence for Smith's murder.

Harlow Cuadra was convicted of murdering Cobra Video founder Bryan Kocis in January 2007 as part of a conspiracy with Joseph Kerekes to seize control of Cobra Video and profit from the career of Sean Lockhart, better known by his stage name Brent Corrigan, whose exclusive contract with Kocis had become the centre of a bitter legal dispute. After killing Kocis inside his Pennsylvania home, Cuadra and Kerekes set the residence on fire in an attempt to destroy evidence and conceal the murder. A lengthy investigation involving DNA evidence, financial records and witness testimony ultimately exposed the conspiracy. Cuadra was convicted of first-degree murder and related offences in 2011 and sentenced to life imprisonment without the possibility of parole.

He later pleaded guilty to murder, was sentenced to 40 years in prison in July 2024, waived his right to appeal and any insanity defense, and remained incarcerated until his death in prison in January 2026 from a self-inflicted injury.

He died in prison in 1991.
