Two brothers have been sentenced to five years in federal prison and a third man was sentenced to 18 months for growing marijuana plants last year in the Uinta National Forest.

"I realize I made a mistake, but the sentence is unjust," Christopher E. Behm told U.S. District Judge David K. Winder.Stephen Peter Behm said Wednesday, "I didn't realize the dire consequences of the sentence."

Winder said the prison term is mandatory because the three Draper men grew more than 100 plants. Prosecutors say the number of plants was 126.

Assistant U.S. Attorney Mark Vincent said the marijuana that was seized had an approximate street value of $250,000.

On Monday, co-defendant Chris R. D'Angelo, 26, Draper, was given only an 18-month prison term because he had cooperated in the investigation.

The men were arrested in September 1990 after a hiker reported marijuana growing in an area between Cascade Springs and the Alpine Loop about 55 miles southeast of Salt Lake City.
