ALLEN PARK, Mich. -- The body of a 41-year-old man was found in a wooded area next to a guillotine he built and used to kill himself, police said.

The man, from the Detroit suburb of Melvindale, was discovered Monday by workers from a shopping center near his home.

Groundskeeper from the Fairlane Green shopping center at Outer and Fairlane drive discovered the body shortly before 11 a.m. Monday.

Allen Park Deputy Police Chief Dale Covert said the roughly six-foot tall guillotine was bolted to a tree and included a swing arm. Covert said police also found several store receipts detailing the materials used to assemble the device.

"I can't even tell you how long it must have taken him to construct," he said. "This man obviously was very determined to end his life."

According to investigators, the man had to make several trips to carry the wooden and metal parts to the area in the woods.

Covert said the man lived within walking distance of the spot where he died.

Police said the man, whose identity police have not released, had been dead for two days.

The man did not leave a suicide note.
