MARSHFIELD — A Marshfield woman accused of supplying fentanyl-laced heroin has entered a not guilty plea, in connection with the death of a Spencer man.

Cassandra Staab, 28, is charged with first-degree reckless homicide and first-degree recklessly endangering safety in the death of 22-year-old Thomas Bychinski on Jan. 31, 2017.

A criminal complaint details how three friends in Spencer obtained and used heroin. The drug that killed Bychinski had two kinds of fentanyl.

When Bychinski’s body was discovered by two friends, one told police that Staab was his source. The man told investigators that he bought heroin from Staab at a grocery store parking lot Jan. 30 and smoked some with Bychinski. Another man, the witness’s brother, said he arranged to purchase one gram of heroin from Staab for $250.

The man said Staab told him the heroin was “very potent, powerful stuff.”

A sentencing date has not been set.
