Heroin, marijuana, cocaine, cash, weapons and a luxury car were seized in busts of two area drug-distribution rings late last week, landing four men behind bars, according to police. Spokane police jailed Andrew Kerr, 19, on Friday. He faces two criminal drug counts after police used an undercover informant to purchase cocaine from him multiple times dating back to September. In a separate bust, three Spokane Valley men were arrested Saturday after members of a local and federal task force discovered heroin prepared for sale at apartments near Mirabeau Meadows.
