With his apparent suicide early Wednesday at the state’s maximum security prison in Shirley, former New England Patriot Aaron Hernandez became the latest high-profile Massachusetts inmate to take his own life.

Here is a look at three other notable cases:

JOHN C. SALVI III — On Dec. 30, 1994, Salvi, dressed in all black, went on a shooting rampage at two reproductive clinics in Brookline, killing two receptionists and wounding five others. He was found guilty of two counts of murder on March 19, 1996, and sentenced to life in prison without parole.

Salvi’s body was found under his cot at MCI-Walpole around 6 a.m. on Nov. 29, 1996, with a plastic trash-can liner over his head, secured by shoelaces.

PHILIP MARKOFF — The so-called Craigslist Killer, Markoff was a Boston University medical student who was charged in the April 14, 2009, murder of a New York masseuse in a Back Bay hotel room. He met the victim, Julissa Brisman, via an ad on Craigslist, the popular online classified website.

Markoff committed suicide on Aug. 15, 2010, in the Nashua Street Jail, where he was awaiting trial. Authorities said Markoff used a pen and a sharp piece of metal to fashion a primitive scalpel and used it to inflict several wounds in his neck, arms, wrists, and ankles, striking his veins and his carotid artery.

JOHN BURBINE — Burbine, a convicted sex offender, had been accused of molesting 13 infants and toddlers while his wife ran an unlicensed child-care business in Wakefield. Most of the assaults, which allegedly occurred from 2010 to 2012, took place in the victims’ homes, authorities said.

Burbine, 50, died March 7, 2014, from injuries sustained in a suicide attempt inside the Middlesex County Jail in Cambridge. He had been found hanging by a sheet in his cell.
