Deputies find cyanide in convicted arsonist's vehiclePosted: Updated:
PHOENIX -- Investigators at the Maricopa County Sheriff's Office say they found new evidence to back the theory that convicted arsonist Michael Marin poisoned himself in court after hearing the verdict.
MCSO deputies found a canister labeled "cyanide" in Marin's vehicle Monday night, more than a week after his death.
Sheriff Joe Arpaio said Tuesday that the family of 53-year-old Marin received a delayed email the night after his June 28 death in court. Arpaio said the email included information about Marin's will in case things went poorly.
Arpaio said the cyanide was purchased for $68 from a California-based supplier in 2011, leading him to believe Marin had been planning his death for months.
"It's really sad," the sheriff said, "You have to feel bad for the family. I don't know why he did it."
Investigators say the cyanide, which the supplier intends for use in gold and silver mining, arrived at Marin's Chandler home in powder form. They believe Marin used the powder to form pellets or capsules, which he brought to court, and ingested moments after the guilty verdict.
The canister was turned over to the medical examiner's office unopened.
All indications point to suicide in Marin's death, but the medical examiner has yet to issue its report with an official cause of death.
Marin collapsed in court and died after being convicted of deliberately burning down his $3.5 million Phoenix mansion.
He was facing up to 16 years in prison.
