A report issued by the law firm that Hennepin County Attorney Mary Moriarty hired to help prosecute a Minnesota state trooper for murder in the shooting of motorist Ricky Cobb II detailed little evidence to counter defense experts’ claims that the shooting was justified.
Moriarty hired the Washington, D.C.-based law firm Steptoe LLP as outside counsel in April and its 858-page “Special Prosecutor’s Report and Recommendations in State v. Ryan Patrick Londregan” was submitted in early June around the time Moriarty dropped second-degree murder charges against Londregan. Steptoe billed Hennepin County $578,321 for 733 hours of work.
The report details how Londregan’s defense was building a use-of-force argument through statements and interviews from the other two troopers on the scene, Brett Seide and Garrett Erickson, along with senior members of the State Patrol who had trained Londregan and were willing to testify that his July 31, 2023, shooting of Cobb as he attempted to flee a traffic stop followed department standards. It also shows how the prosecution’s own use-of-force expert ultimately determined that Londregan was likely justified in his decisionmaking because he feared for the safety of Seide, who had half of his body in the driver’s side window when Cobb shifted his car into drive.
Many of those witnesses also went before a grand jury. That testimony was redacted from the report, though the Hennepin County Attorney’s Office argued unsuccessfully in court that it should be released.
All of that information was available to Moriarty before she hired Steptoe and before a hearing on April 29 where Londregan’s attorney, Chris Madel, said they would argue that Londregan feared Cobb was reaching for Londregan’s gun.

The Steptoe report zeroes in on that piece of information as a turning point in the ability to successfully prosecute Londregan. Moriarty told the Star Tribune in June it changed her belief that she should continue pursuing the case.
A spokesperson for the Hennepin County Attorney’s Office said, “In a community where police violence has impacted so many, it would have been unfathomable for us to simply decide to drop a case that at the time we believed we could prove beyond a reasonable doubt. Eventually, that calculus changed, and that is the point at which we dismissed the charges.”
Madel said in an interview this week the notion that Moriarty was surprised by any element of their self-defense argument rang hollow.
