INNISFIL, Ont. - Two Innisfil, Ont., men are now charged with manslaughter in an overdose death from earlier this year.

South Simcoe Police say the 23-year-old victim, also from Innisfil, died in early April after overdosing on heroin and fentanyl.

Shortly after the death, police arrested the men who allegedly supplied the drugs and charged them both with trafficking in fentanyl and heroin.

After further investigation and consultation with prosecutors, however, police laid the additional charge on Wednesday.

They say the men, 23 and 55, are jointly charged with manslaughter and are being held in custody.

No names were released.
