Police and relatives have described the confrontation differently, leaving prosecutors to assess video, witness statements and the circumstances of the gunfire.
SEATTLE, Wash. — Nearly three weeks after a Belltown shooting killed Isaac Rios and critically wounded Matthew Lanske, Seattle police released a reconstruction that differed in important ways from the first family accounts, replacing an initially reported armed-robbery narrative with a more detailed description of an argument, a renewed confrontation and a physical fight involving an armed man.
The difference does not mean investigators have said the families were intentionally wrong. It reflects how the public account of a fast-moving homicide can change as detectives gather video, interview participants and compare witness statements. Lanske’s relatives initially said he was shot while trying to stop a gunpoint robbery involving his friend. Police later said their evidence showed a series of interactions that culminated in a fight, but their Sept. 23 statement did not say what the dispute was about and did not confirm an attempted robbery. The department said the completed investigation would be referred to King County prosecutors for review and possible charges.
The police timeline starts before the gunfire. Detectives said that at approximately 12:29 a.m. Sept. 6, a 20-year-old man interacted with a 20-year-old woman near Third Avenue and Clay Street as people and vehicles were assembling for an illegal street takeover. The woman was accompanied by a 22-year-old man and a 26-year-old woman. Police said the interaction became a brief hostile argument. Witnesses became aware during that exchange that the 22-year-old man had a gun, according to the department. The two sides then separated, but the separation did not end the encounter.
About nine minutes later, police said, the 20-year-old man and a 21-year-old companion approached the other group. Detectives described the next event as a physical fight involving the armed 22-year-old man. Police said he momentarily broke free and tried to move away but was caught and the fight continued. During that struggle, the firearm discharged several times and struck three people, according to the department. At some point the gun became separated from the fight and was picked up by the 20-year-old man, who walked away with it. Police said the weapon had been legally possessed by the 22-year-old before the confrontation.
That police description placed new uncertainty around the early robbery account. In interviews immediately after the shooting, Lanske’s family said he and friends had just finished dinner when a man and two women tried to rob one of his friends at gunpoint. His sister, Rebecca Garberding, said Lanske attempted to wrestle the gun away and was shot. Relatives of Rios also said they believed a robbery had occurred. When FOX 13 Seattle asked police after the Sept. 23 update whether the robbery description was accurate, the station reported that the department had not responded by that night. Police also did not explain publicly what caused the earlier hostile interaction.
Whatever prosecutors ultimately conclude about the confrontation, its physical cost is not in dispute. Rios, 20, suffered gunshot wounds and was found in the 300 block of Clay Street. Officers provided aid until Seattle Fire Department medics took over, and he was transported to Harborview Medical Center. He died despite lifesaving efforts. Police found Lanske, 21, in the 300 block of Denny Way with gunshot wounds to his abdomen. His family said he had been hit three times, including a shot that shattered his pelvis and damaged a major artery. Police described him as critically injured in the later update.
The other participants also became part of the investigation. Police said a 22-year-old man and a 26-year-old woman went to Harborview after the shooting with leg injuries. Detectives interviewed them and another 20-year-old woman. By Sept. 23, investigators said all people directly connected with the events surrounding the shooting had been identified. That assertion marked a change from the earliest days, when police were asking for information that could lead to an arrest. Yet identification did not immediately produce a public arrest announcement, underscoring that knowing who took part in an encounter is different from determining whether the evidence supports a criminal charge.
The shooting’s aftermath produced another set of allegations separate from the question of who was legally responsible for the gunfire. Lanske’s mother, Shanda Barney, said her son walked nearly two blocks while badly wounded trying to find someone who would help. She said he later told her that he reached a 7-Eleven, pleaded to be let inside and found the doors locked. Barney also said bystanders stood nearby recording or photographing him rather than assisting. Those claims were reported through the family’s interviews. Police have not announced an investigation accusing store employees or bystanders of wrongdoing, and available reports do not provide independent accounts from the workers about their decisions that night.
Lanske eventually contacted 911 and his girlfriend, according to his family. Police located him, and he was taken to Harborview. Barney said he remained on life support for two days before regaining the ability to communicate. His family said he underwent multiple surgeries and faced months of recovery before he could return to his construction job. Their initial public appeal focused heavily on witnesses, asking anyone who had seen or recorded the confrontation to provide information. That appeal intersected with the police investigation as detectives began gathering an expanding body of digital evidence.
Video became one of the reasons police said they could later clarify the sequence. The department cited footage from its Real Time Crime Center, neighboring businesses and numerous community members, along with statements from the people involved. Seattle police also opened an online portal specifically for evidence from the street takeover and shooting, allowing members of the public to submit photographs and recordings anonymously. The videos, police said, helped investigators identify participants and understand the movements before and during the fight. The department has not publicly released all of the evidence it relied upon.
The location and surrounding activity also shaped the investigation. KIRO 7 cameras captured vehicles performing maneuvers in the intersection and a crowd gathering as fireworks were set off during the street takeover. Residents said the gatherings had occurred before and complained that the activity had escalated. The shooting that killed Rios came at the beginning of a violent period in Belltown: another woman was fatally shot in a separate incident less than two hours later, and a teenage boy was killed in another shooting later that night. Police have treated those as separate investigations rather than a single criminal event.
Rios’ relatives have continued to question how the violence unfolded and whether it could have been prevented. Family and friends created a memorial for him near the scene, and his mother publicly demanded answers after police released the new chronology. She also questioned the response to the street takeover before the shooting, saying the city had received earlier calls. Police reporting reviewed for this article does not establish that an earlier dispatch would have prevented the confrontation. Rios’ obituary described him as an Everett native who grew up around Seattle and was known for his close ties to family and friends.
The case now rests on legal questions the public evidence does not fully answer. Prosecutors reviewing a fatal shooting may weigh who initiated force, what participants reasonably perceived, how possession and use of the firearm unfolded and what the available video and witness statements establish. Seattle police have not publicly announced such conclusions in this case. Their Sept. 23 update described conduct and evidence without declaring that any identified participant committed murder, assault, robbery or another offense. That restraint matters because an investigative reconstruction is not the same thing as a charging decision or a finding of guilt.
What remains unresolved is not the identity of the people involved but the legal meaning of their actions. Detectives say video and witness statements allowed them to establish a sequence that included an earlier argument, a second confrontation, a physical fight and repeated gunfire. That evidence has not yet produced a publicly announced charging decision, and police have not confirmed the families’ early description of an attempted robbery. The prosecutor’s review will determine whether the reconstructed events support criminal charges.
