A Chicago man and a Wisconsin woman were arrested after officers found them with a large amount of cocaine, fentanyl and other drugs at a motel in Crystal Lake.

Bryce Casper, 22, of Lake Geneva, Wisconsin, was charged with two counts of possession of a controlled substance with intent to distribute, four counts of possession of a controlled substance and one count of drug paraphernalia.

A second suspect, Michael R. Mantor, 48, of Chicago, was charged with three counts of possession of a controlled substance with intent to distribute, four counts of possession of a controlled substance and one count of drug paraphernalia.

A criminal complaint filed in McHenry County Circuit Court said Casper and Mantor possessed with the intent to deliver over 15 grams but less than 100 grams of a substance containing cocaine as well as 15-100 grams of a substance containing fentanyl.

The complaint said Casper and Mantor were found in possession of less than five grams of a substance containing methamphetamine and less than 200 grams of psilocybin.

Mantor and Casper were additionally found in possession of digital scales and glass containers with white residue, the complaint said.

The two were arrested by the McHenry County Sheriff’s Office around 1:30 pm. on January 24.

A sheriff’s office spokesperson said the drug bust occurred at the Super 8 by Wyndham, 577 Crystal Point Road in Crystal Lake.

The most serious charges against the two are Class X felonies, which carry six to 30 years in the Illinois Department of Corrections.

The McHenry County State’s Attorney’s Office filed petitions to detain Casper and Mantor pending trial, calling them real and present threats to the community and flight risks.

Prosecutors said Mantor was out on pre-trial release in another Class X drug case out of McHenry County at the time of the offense.

McHenry County Judge Michael Chmiel ordered both detained in the McHenry County Jail after granting the petitions.

The judge said he found by clear and convincing evidence that Casper and Mantor committed the offenses and that they were willful flight risks.

Preliminary hearings are scheduled for February 23.
