RJ T. Marinas, 33, of Rockford.

A Rockford man has been arrested on a $1 million warrant for allegedly selling fentanyl to a 30-year-old woman, causing her overdose death in Woodstock.

RJ T. Marinas, 33, of Rockford, was charged with one count of drug-induced homicide, a Class X felony.

A criminal complaint filed in McHenry County Circuit Court said that Marinas delivered a substance containing fentanyl to a woman on June 4 in Rockford.

The woman, Cassandra E. Tomassi, 30, of Belvidere, inhaled a portion of the substance into her body.

She was found dead the next day in Woodstock, the complaint said.

The case was investigated by the Woodstock Police Department and charges were filed in McHenry County Circuit Court against Marinas on December 14.

Marinas was taken into the custody of the McHenry County Jail Tuesday morning.

An obituary for Tomassi said she graduated from Belvidere High School in 2009.

She enjoyed being outdoors and exploring nature. Tomassi liked hiking, kayaking and rock collecting, her obituary said.

Marinas is being held on a $1 million bond, which was set when the warrant was issued.

He would need to post $100,000 cash in order to be released.

Marinas is scheduled to appear in court on Friday.
