Former Colts Player Arrested On Federal Charges

Deputies booked Muir into the Pulaski County Jail on Aug. 20 after federal prosecutors filed two charges against him.

Prosecutors accuse Muir of making a false statement to a licensed firearms dealer and providing false information on Form 4473, the federal document used during firearm background checks, according to WTHR.

Prosecutors filed the charges back on May 22 but kept the case sealed until Muir’s arrest this week. No federal court date has been set yet, and authorities haven’t released further details about the charges.

These federal charges sit separately from Muir’s existing Indiana case. Prosecutors already charged him with obstruction of justice, domestic battery, and battery resulting in serious bodily injury in Cass County, stemming from his teenage son’s disappearance in June 2024.

The boy’s grandmother reported him missing after noticing visible injuries, and authorities located him roughly three weeks later during a raid on the Muirs’ Logansport property. Prosecutors separately charged Muir’s wife, Kristin, with obstruction of justice tied to the same case.

Both Trials Now Face A Late-September Court Date

Court officials pushed back Muir’s Indiana trial, originally scheduled for earlier this year, to Sept. 28, 2026. They rescheduled Kristin Muir’s trial for the same date. Cass County prosecutor Noah Schafer said his office would continue working with defense attorneys to finalize the new timeline following Muir’s federal arrest.

Muir spent parts of seven NFL seasons with six different teams, including four years with the Colts from 2008 through 2012, as well as stints with the Rams, Jets, Chiefs, Texans, and Raiders.

He racked up 128 total tackles and 1.5 sacks across 56 games. Legal troubles involving former Colts players have surfaced on multiple occasions in recent years. Police also arrested former offensive lineman Joseph Staysniak in 2023 on strangulation and battery charges connected to a confrontation involving his own son.

The Colts organization holds no current affiliation with Muir, and his case remains entirely separate from the team’s ongoing preseason preparations. As with any pending case, the federal charges against Muir remain allegations unless prosecutors prove them in court.
