Justin Blackshear was convicted Wednesday of first-degree murder in the stabbing deaths of two former co-workers at Cheli's Chili Bar, a restaurant owned by Red Wings defenseman Chris Chelios.
The 18-year-old Blackshear, who had been fired twice from his job as a busboy, previously had confessed to killing chef Mark Barnard and restaurant manager Megan Soroka on January 2.
A jury at Wayne County Circuit Court needed approximately three hours to return a guilty verdict after hearing evidence that included the confession, more than $7,000 stolen from the restaurant and DNA samples taken from Blackshear's jeans and an envelope in his apartment.
Blackshear will be sentenced to life without parole on September 7.
