The scene inside a Colorado courtroom looked a grim picture of human action on Friday as a young and condemned man testified to his onetime best friend’s alleged glee in violence.

Joseph Edwin Koenig, 20, was a high school senior, but 18 years old, when he and two friends were charged with “extreme indifference” murder over the April 19, 2023, death of Alexa Bartell, 20.

On the day in question, the windshield of the victim’s Chevy Spark was struck and smashed by what authorities termed a “large landscaping rock.” The impact sent the young woman’s car careening “off the roadway” on a remote stretch of road in Jefferson County.

Bartell died a horrible death in the ensuing crash; prosecutors previously testified the victim’s brain was found in her backseat.

A Texas teenager who allegedly stabbed another teenager to death during a high school track meet told police that he acted in self-defense.

In an arrest affidavit obtained by local ABC outlet WFAA, police said that following the alleged incident, suspect Karmelo Anthony, 17, told officers, “I was protecting myself.”

As he was led away from the scene, the defendant reportedly stated, “He put his hands on me, I told him not to.”

Local CBS affiliate KBTX also reported on the arrest affidavit, which contained several redacted names of almost 30 students who were witnesses to the alleged altercation.

Mihaela Gabriela Sorescu, 16, who also uses the name Bella, is Mottram’s daughter. The other suspect, Abigael Paige Flanagan, 17, who also uses the name Jay, was also staying at the home at the time. Police said in probable cause affidavits for both girls that they are “unaccounted for at this time.”

The teenager charged with accidentally shooting his friend in the head with a handgun during a session of gaming and smoking marijuana pleaded not guilty to a charge of involuntary manslaughter on Tuesday, according to Cowboy State Daily.

Luka Wade Rasmussen, 18, must remain behind bars on $500,000 bond after the judge rejected a defense request to have his bail lowered to $100,000. Public defender Marty Scott reportedly noted that the teenager’s coworkers at Wendy’s wrote a letter attesting to his character. District Attorney Dan Itzen, however, noted the seriousness of the charge and alluded to the claim that one of the three guns located on the property and been reported stolen in summer 2024.

The victim, Riley Jacob Sears, 16, had joined Rasmussen and a teenager who lived in the home on Feb. 12, 2025, in Casper, Wyoming. They played video games and smoked marijuana, authorities said, but at one point, Rasmussen took out a gun, and it went off, authorities said.

St. Petersburg police Chief Anthony Holloway told reporters at a press conference that there was a dispute over some missing jewelry on Feb. 20. Gress and Brandes allegedly assaulted and tortured Miranda for the next week.

“Repeatedly beat the victim, while holding her captive for seven days and eventually suffocating her by wrapping plastic wrap around her face,” a judge said during Gress’ first appearance, according to local NBC affiliate WFLA.

Gress and Brandes then put the teen’s body in his car and drove the remains some 15 miles to a home in the 12000 block of Mallory Drive in Largo. There, police believe she was dismembered. Her remains were once again moved, this time to a dumpster about 55 miles away across Tampa Bay. Cops have located the dumpster, however the remains were disposed into a Hillsborough County landfill. Cops are continuing to search for Miranda’s body.

Miranda’s grandmother, who had custody of her after both of her parents died, reported her missing to Gulfport police on Feb. 24.

She also was the mother of a 11-month-old child. Her grandma told police Miranda was known to run away and she’d usually return home, but not this time.

On Thursday, a “witness” contacted police regarding information about a kidnapping and homicide. Police realized they already had Gress in custody after he allegedly pointed a harpoon at Brandes and was in possession of drugs. Detectives quickly unfurled the horrific case. Brandes turned herself into cops on Saturday.
