The Michigan Corrections Department says prison guards' failure to reset motion-detection alarms played a "major role" in a convicted quadruple killer's escape last month.
An investigatory report released Thursday says two zones at a prison vehicle entrance weren't secured at the start of a shift at the Ionia Correctional Facility east of Grand Rapids. Inmate Michael Elliot crawled under fences and escaped for 24 hours before being captured in Indiana.
The state says Elliot began to think seriously about an escape due to heavy snow he thought would provide cover. And he ultimately chose Super Bowl Sunday because he thought staff might be distracted. But investigators found no evidence that was the case.
Investigators also found no evidence Elliot had help from other inmates or staff.
