What do the rideshare records show in Shannon O’Brien’s killing?

What did police report finding on January 30?

RiverBender, citing information St. Louis County police released on October 5, 2026, reported that Ferguson police answered a shots-fired call in the 1700 block of Windward Court shortly before 4 p.m. Officers found O’Brien, 28, with a gunshot wound in the driver’s seat of a blue Hyundai Elantra. She died at the scene. RiverBender reported that she was an Edwardsville High School graduate.

The same story said previously released probable-cause statements reported that O’Brien had transported three passengers to the location in her Lyft. Investigators alleged that those passengers were involved in the conflict and that gunfire erupted between their group and people in a Chevrolet Malibu.

First Alert 4’s September 29, 2026 story is consistent on one point and is not a charging document. It reported that prosecutors said O’Brien was in the area to drop off three people when passengers in another car began shooting, and that the passengers were the reported targets.

What do the rideshare records show?

RiverBender’s account of the probable-cause statement separates two kinds of proof.

Video and rideshare records, the statement said, showed Damien Stevens fleeing with co-defendant Lamarkus Van. The previously released statements, as RiverBender described them, said O’Brien transported three passengers in her Lyft. Those records, as described, place people in the car and identify who left together.

They are not described as the proof of an agreement. The alleged agreement is attributed to a different search. Investigators said a search of a co-suspect’s phone revealed an agreement between members of opposing groups to meet and resolve a conflict through a shootout. RiverBender attributed that sentence to the probable-cause statement. It is an allegation. It is not a finding. It is not something the rideshare records are described as proving.

The same account said Stevens and others had an ongoing conflict with a group identified as the VonniGang, that investigators recovered a firearm with distinctive modifications, and that the statement alleges an Instagram photo of Stevens holding a firearm that strongly resembled it. Those are allegations in the statement as RiverBender reported them.

What charges did the October 5 report list?

The list below is RiverBender’s October 5, 2026 account of police and prosecuting-attorney information. Charging documents were not reviewed. Bonds are amounts the story reported, not a later court order confirmed here.

• Damien Stevens, 18, of Florissant, was certified as an adult on October 1, 2026, and charged that day. The prosecuting attorney’s office charged second-degree felony murder, two counts of armed criminal action, and first-degree assault. RiverBender reported a $1 million cash-only bond, with no 10 percent option.
• Kamarionne Carter, 17, was certified as an adult and charged September 29 with second-degree murder, two counts of armed criminal action, and unlawful use of a weapon. RiverBender reported a $1 million cash-only bond. First Alert 4 reported the same counts and said Carter was certified that Tuesday.
• Lamarkus Van, 17, was certified as an adult and charged August 10 with second-degree murder, two counts of armed criminal action, and first-degree assault or attempted assault. RiverBender reported a $1.5 million cash-only bond.
• Cortez Alexander, 17, was certified as an adult and charged July 22 with the same charges as Van. RiverBender reported a $1 million cash-only bond.
• Noah Johnson, 18, was charged March 17 with first-degree murder, two counts of armed criminal action, and aiding or abetting a person shooting at or from a motor vehicle resulting in physical injury or death. RiverBender reported a $750,000 cash-only bond.

RiverBender’s March 18, 2026 story, citing the probable-cause statement, reported that after Johnson was advised of his rights he confessed to being one of the shooters from the Malibu, and that the interview indicated the three passengers in the Elantra were the intended targets. “Confessed,” in that sentence, is what the statement said according to RiverBender. It is not a court finding. The October 5 story did not update that account to a plea or a conviction. The March story also said O’Brien was once a member of the Edwardsville Tigers’ girls cross country team.

What is still unverified?

No charging document, warrant, or docket was reviewed. No source reviewed here reports a plea, a dismissal, or a conviction after October 5, 2026. Status after that date is unverified.

The booking and rideshare records, as the October 5 story described them, answer who was in the Lyft and who left with whom. They do not, on that description, establish the alleged agreement. That allegation stays tied to the phone search in the probable-cause statement.
