2d state chemist charged with drug tampering

Sonja Farak, 35, of Northampton, allegedly tested two samples, believed to be heroin and cocaine, on Jan. 2 and Jan. 8 and then replaced the drugs with counterfeit substances, Attorney General Martha Coakley told reporters at an afternoon news conference.
