The Bayfield County (Wis.) Sheriff's Department says a 61-year-old Michigan man working on a Lake Superior ore boat was killed after he became caught in a conveyor belt and was crushed.

The victim was identified as Denton Heske of Harrison, Mich. The Coast Guard and emergency personnel from Bayfield County traveled to the ship about 9 p.m. Sunday after the accident was reported on the Stewart J. Cort, a 1,000-foot ore boat 10 miles northwest of Devil's Island.

Medical personnel and others on the boat tried but failed to resuscitate Heske.

Authorities from Bayfield County and the Coast Guard station in Duluth investigated and determined Heske's death was accidental.

The Minnesota Bureau of Criminal Apprehension on Monday released the name of the Duluth police officer who shot and killed a teenager after responding to a disturbance call late Thursday night.

Jeffrey Keast, 30, a three-year member of the department, is on a paid administrative leave, standard department policy after an officer-related shooting.

The preliminary investigation by the BCA found that when Keast arrived at the scene of a disturbance call, Joseph Anthony Carl, 17, approached Keast's squad car and repeatedly struck the vehicle with a baseball bat.

Keast backed up the squad car, sideswiping a parked vehicle, then came to a stop. Carl then shattered Keast's driver's side window with the bat and continued to attack while Keast was still in the car, the BCA determined.

Keast fired a single shot, striking Carl, who retreated. The officer then radioed for medical help. He and other arriving officers administered CPR until medical personnel could take over. Despite those attempts, Carl died at the scene.

A 30-year-old Mankato man convicted of causing about 25 fractures to his infant son has been sentenced to 14 years in prison.

Olmsted County District Judge Kevin Lund told Robert Lee Heck III Monday afternoon that he will have to serve two-thirds of the 171-month term in prison before being eligible for parole.

In May, Heck was convicted of first-degree assault for causing 25 fractures to his 6-week-old old son, Jordan, in January 2007.

Jordan and his twin brother, Jacob, were born conjoined in Rochester. They were premature and surgically separated shortly after birth. Jordan was released from the hospital on Jan. 3, 2007. Heck and the infant's mother, Valerie James, lived at the Ronald McDonald House in Rochester with the infant in order to continue to visit Jacob, still in the hospital. Seven days after his release, Jordan was back in the hospital. Doctors said he had fractures to his legs, arms and ribs.

Lund told Heck that no sentence can repair the damage to Jordan, his twin, or their older sister. "It was all wrought by your reprehensible conduct," the judge told Heck.
