Whitey Bulger never got his last wish.

The notorious gangster, who was bludgeoned to death with a padlock stuffed in a sock Oct. 30, hours after being transferred to a West Virginia federal jail, had dreamed of peacefully dying in his sleep, letters obtained by the Boston Globe show.

In a July 2017 letter sent to former convict Charlie Hopkins, 86, of Florida, the ex-South Boston crime boss wrote about rebuffing an offer to be taken to a hospital over worsening health problems.

“I prefer to stay here and hope to get a peaceful death,” Bulger wrote. “One of those he Died in his Sleep kind.”

But instead of waiting out his time in the US Penitentiary Coleman 2 in Florida, the Winter Hill gang boss was transferred to the US Penitentiary Hazelton, where he was killed by other inmates.

The series of letters sent over the past several years to Hopkins list the litany of 89-year-old Bulger’s health issues, including several heart attacks and blackouts.

“He told me three or four times in the past 18 months that he was having blackouts,” said Hopkins, a former Alcatraz inmate. “A couple of times he felt sure that he was dying. He was able to get a nitro pill in his mouth and that would start bringing him out of it.”

In one letter, from May 2017, Bulger also said he dreaded going back to the hospital.

“Its in town and naturally lots of security — shackles and chains through them and into end of the bed and left hand with cursed black box invented by some ‘inmate’ with heavy padlock,” he wrote. “I’ve been in that situation 3 times — heart attacks — have had 4 — running out of my 9 lives.”

Instead, he wrote he “would like to get one of those easy deaths.”

“Go in your sleep no black box and hospital wouldn’t be an ordeal,” he wrote.
