Two men have been arrested in Friday night's double homicide discovered in the parking lot of the Owosso Walmart.
A 31-year-old suspect was arrested Saturday night and his 23-year-old brother was arrested Sunday morning in Grand Rapids.
The Grand Rapids Police Department assisted Michigan State Police with one of the arrests.
31-year-old Joseph Michael Carson and 39-year-old Anthony Lee Hammond were found dead inside a vehicle Friday in the Walmart parking lot.
Carson and Hammond are both from Flint.
Police say Carson and Hammond were meeting the two brothers in the Walmart parking lot to sell marijuana. That's when the brothers decided to rob and shoot at their vehicle.
The men all met through a posting on Craigslist.
Michigan State Police continue to investigate the double homicide.
Both suspects are expected to be charged later this week. They're currently sitting in the Shiawassee County Jail.
