A major Detroit-area drug trafficker known as "White Boy Rick" who has spent nearly 30 years in prison for crimes going back to his teen years is expected to face a judge reconsidering his life sentence.

Forty-six-year-old Richard Wershe Jr. is to appear Friday morning before Wayne County Circuit Judge Dana Hathaway.

Wershe was arrested in 1987. Prosecutors said he had cocaine before his arrest but dumped it in a neighbor's yard before being apprehended.

Wershe was convicted of possessing more than 650 grams of cocaine and was 18 when sentenced to life in prison without parole. Changes in Michigan's drug law made him eligible for parole.

At the time, authorities described Wershe as being at the top echelons of trafficking.

Defense attorney Ralph Musilli says his sentence is unconstitutional.
