ICE Agent's'Dragging' Case May Help Expose Evidence in Renee Good Shooting The government has withheld details of the investigation of Renee Good's killing--but an unrelated case involving the ICE agent who shot her could force new revelations. Defense attorneys for a Minnesota man convicted in December of assaulting Immigration and Customs Enforcement officer Jonathan Ross are seeking access to investigative files related to the killing of Renee Nicole Good, after learning Ross was the same officer who shot and killed her during a targeted operation in Minneapolis last month. Attorneys for Roberto Carlos Muñoz-Guatemala asked a federal judge on Friday to order prosecutors to turn over training records as well as investigative files related to Ross, the ICE agent who killed Good on January 7 during Operation Metro Surge and was also injured in a June 2025 incident in which Muñoz-Guatemala dragged him with his car. A separate post-trial motion by the defense, filed in the US District Court in Minnesota, asks the judge to pause deadlines for a new-trial motion until the discovery motion is resolved. Muñoz-Guatemala's attorneys argue that even if the court ultimately decides that any newly discovered evidence doesn't entitle their client to a new trial, he's entitled to explore whether there are mitigating factors that could impact the length of his sentence, such as whether Ross' injuries could have been, to some degree, brought upon him by his own behavior.

In a game of scientific telephone, if you find the food, you find the whales--and sound the alarm. North Atlantic right whales sometimes gather at Jeffrey's Ledge, a 62-mile-long underwater ridge about 25 miles off the coast of Portsmouth, New Hampshire. Breakthroughs, discoveries, and DIY tips sent six days a week. It was a cold and windy week last January, when a group of Maine lobstermen couldn't haul in their traps from Jeffrey's Ledge. The reason why surprised everyone.

After an ICE agent shot and killed the Minneapolis mother, conservative media launched an all-out attack on her reputation. Her identity as a queer woman was central to it. Renee Nicole Good was a poet, a mother of three, a wife. Within hours of her death, as far as the government was concerned, she was a domestic terrorist . She appeared to have four gunshot wounds, according to The New York Times, which cited a Minneapolis Fire Department report.

A contract justification published in a federal register on Tuesday says that 31 ICE vehicles operating in the Twin Cities area "lack the necessary emergency lights and sirens" to be "compliant." Paul area "currently lack the necessary emergency lights and sirens" required to be "compliant with law enforcement requirements," according to a contract justification published in a federal register on Tuesday. The document justifies ICE paying Whelen Engineering Company, a Connecticut-based firm specializing in "emergency warning and lighting technology," $47,330.49 The document explains that the ATLAS kits would "allow vehicles to be immediately operational and compliant with law enforcement requirements to support the current surge operation" out of Homeland Security Investigations (HSI)'s St. Paul office, which conducts operations in Minnesota, North Dakota, and South Dakota. "These vehicles were deployed prior to being permanently retrofitted and currently lack the necessary emergency lights and sirens required for operational use," the document says.

FBI Agent's Sworn Testimony Contradicts Claims ICE's Jonathan Ross Made Under Oath The testimony also calls into question whether Ross failed to follow his training during the incident in which he reportedly shot and killed Minnesota citizen Renee Good. In testimony last month in federal court in Minnesota, FBI special agent Bernardo Medellin appeared to directly contradict a claim that ICE agent Jonathan Ross made under oath about whether a man they were trying to detain had asked to speak to his attorney. Medellin's testimony, which details federal training for interactions with drivers, also calls into question whether Ross followed his training during the interaction that led to the shooting and killing of Renee Nicole Good, a 37-year-old mother, last week. Ross has been identified by multiple media outlets as the shooter; while the Trump administration has declined to confirm those reports, details about the shooter shared by Vice President JD Vance match details of Ross' biography. As WIRED previously reported, in December Ross testified that last June he led a team seeking to apprehend a man named Roberto Carlos Muñoz-Guatemala, who had an administrative warrant out for being in the US without authorization.

Jonathan Ross told a federal court in December about his professional background, including "hundreds" of encounters with drivers during enforcement actions, according to testimony obtained by WIRED. Jonathan Ross, the Immigration and Customs Enforcement officer identified by multiple news outlets as the federal agent who shot 37-year-old Renee Good in Minneapolis on Wednesday, is a veteran deportation officer in ICE's Enforcement and Removal Operations division, according to sworn testimony from the federal district court in Minnesota obtained by WIRED. A member of a Special Response Team, ICE's version of a SWAT team, he's had duties as a firearms trainer and led teams drawn from multiple federal agencies including the FBI, Ross testified. The testimony stems from a December 2025 trial related to a June incident with parallels to the interaction that led to Good's killing. In June according to Ross's testimony, he led a team seeking to apprehend a man named Roberto Carlos Muñoz-Guatemala, who was on an administrative warrant for being in the United States without authorization.

The home space for optimal control is a Sobolev space. The home space for pseudospectral theory is also a Sobolev space. It thus seems natural to combine pseudospectral theory with optimal control theory and construct ``pseudospectral optimal control theory,'' a term coined by Ross. In this paper, we review key theoretical results in pseudospectral optimal control that have proven to be critical for a successful flight. Implementation details of flight demonstrations onboard NASA spacecraft are discussed along with emerging trends and techniques in both theory and practice. The 2011 launch of pseudospectral optimal control in embedded platforms is changing the way in which we see solutions to challenging control problems in aerospace and autonomous systems.

This paper derives various Hessians associated with Birkhoff-theoretic methods for trajectory optimization. According to a theorem proved in this paper, approximately 80% of the eigenvalues are contained in the narrow interval [-2, 4] for all Birkhoff-discretized optimal control problems. A preliminary analysis of computational complexity is also presented with further discussions on the grand challenge of solving a million point trajectory optimization problem.
