Twenty-four-year-old Jonathan Blair Copeland, of the 100 block of Old Elm Road in North East, and 28-year-old John Wallace Green III, of the unit block of Maple Hill Court in Port Deposit, were both charged with first-degree murder.
Police said Copeland accused Myers of stealing a large quantity of drugs and money from his home on Monday and, in front of other people, threatened to kill Myers.
The amount of money was "thousands of dollars," police told the Cecil Whig.
At 4:50 p.m. Wednesday, police said they found Myers dead inside his Ford truck at the end of his driveway in the 1500 block of Principio Road. Police said he died from multiple gunshot wounds.
At least one witness saw a man matching Green's description shoot into the truck, according to the sheriff's office.
Witnesses reported seeing a black Ford Mustang, which is the type of a car Copeland frequently drove; it was registered to an acquaintance who was not a suspect, according to Lt. Michael Holmes of the Cecil County Sheriff's Office.
Copeland and Green reportedly drove to Newark, DE, where they had car troubles, so a friend towed them back to Cecil County.
The sheriff's office found Copeland in the parking lot of M&T Bank in the 2800 block of Tome Highway Wednesday night; he was charged with first-degree murder on Thursday.
Green was arrested at his home in Port Deposit and charged with first-degree murder Friday, according to Holmes.
