Police say they served a warrant on a home and a vehicle located on the 700 block of N Van Buren Street as part of an ongoing firearms investigation.
It was during their search that a K-9 officer was alerted to the presence of narcotics inside the vehicle. That's when officers discovered a trap door on the car, which was concealing a loaded .40 caliber handgun and more than two thousand bags of heroin.
Upon further investigation, it was found that the firearm had been reported stolen to the New Castle County Police Department.
The suspects, identified by police as 23-year-old William Comer and 50-year-old Kenneth Stewart, have prior drug convictions.
Comer is on probation and is a 12-time convicted felon, for crimes including robbery, assault and drug dealing.
Stewart is a parolee who has four felony convictions for drug dealing and burglary.
Both Comer and Stewart are awaiting arraignment at Wilmington police headquarters on charges including heroin trafficking, carrying a concealed weapon, possession of a stolen firearm and conspiracy.
