A Casper man has admitted that he was in possession of an illegal substance.

Neil Arcuri has pleaded guilty to one count of possession of a controlled substance marijuana.

Investigators with both the Casper Police Department and the Wyoming Division of Criminal Investigation say in middle December 2015, officers met with a known but unnamed reliable confidential informant, who said he/she had observed a large marijuana grow in the basement of a residence on the 300 block of Oleander Street, in southwest Casper.

After obtaining a search warrant, investigators were able to confirm that the information was accurate and found a multi stage marijuana grow operation, set up to be top of the line and of high quality.

Agents collected 54 suspected marijuana plants, and the buds of the plants weighed more than 375 grams without packaging.

Another confidential informant said that he/she was buying quantities of marijuana from Arcuri three-to-four times a week for the past three months.

As part of a plea deal, prosecutors dropped two other charges against Arcuri (one count of possession of a controlled substance marijuana with intent to deliver, and one count of cultivating a controlled substance marijuana), and will seek a term of probation.

Arcuri is free on $20,000 bond and will be sentenced at a later date.
