Gang Member Pleads Guilty to Illegal Possession of Firearm

SPRINGFIELD, Mo. – A Springfield, Mo., man pleaded guilty in federal court yesterday to illegally possessing a firearm.

Jayden Isaac Simmonds, 19, pleaded guilty before U.S. District Judge M. Douglas Harpool, to being an unlawful user of a controlled substance while in possession of a firearm.

Simmonds admitted to possessing a stolen Smith and Wesson 10mm semi-automatic pistol and daily use of marijuana and opioid addiction. Simmonds also admits to being a member of a local gang known as the “1500.”

According to an affidavit filed with the original complaint charging Simmonds with being an unlawful user of a controlled substance, investigators test-fired the pistol and submitted the casings to the National Integrated Ballistic Information Network (NIBIN) for analysis. The test-fired cartridges, the affidavit says, were a presumptive match to shell casings recovered from two separate shootings in Springfield in August 2024. The first shooting occurred on Aug. 4, 2024, on West Brower Street. An occupied residence was shot multiple times by unknown suspects. At least 17 rounds struck the residence, but there were no injuries. The second shooting occurred on Aug. 14, 2024, on North Prospect Avenue. A disturbance resulted in shots being fired. One residence was struck, but there were no injuries reported.

Following his arrest, Simmonds told investigators he had been using marijuana daily since he was 11 or 12 years old, and that he was addicted to opioids and had been using fentanyl.

Under federal statutes, Simmonds is subject to a sentence of up to 15 years in federal prison without parole. The maximum statutory sentence is prescribed by Congress and is provided here for informational purposes, as the sentencing of the defendant will be determined by the court based on the advisory sentencing guidelines and other statutory factors. A sentencing hearing will be scheduled after the completion of a presentence investigation by the United States Probation Office.

This case was prosecuted by Assistant U.S. Attorney Stephanie L. Wan. It was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Christian County, Mo., Sheriff’s Department and the Springfield, Mo., Police Department.
