NORFOLK, Neb. (AP) — A 42-year-old northeast Nebraska man is suspected of trying to send drugs to a prisoner at a federal prison in Texas.

Miguel Monzon has been charged with intent to distribute methamphetamine and heroin.

In court records, a postal inspector says Monzon was seen on Sept. 26 at the Norfolk, Nebraska, post office mailing a parcel to the prison in Beaumont, Texas. Investigators say they found heroin and meth inside the package.

Monzon’s lawyer last week entered a plea of not guilty for him. Monzon already has spent 35 months in a federal prison on an earlier drug conviction.
