​'Violent weekend': Austin tops last January's murders with two double homicides, stabbing over weekend

Austin police are now investigating two double homicides and a separate stabbing death after a "violent weekend" left five dead in the city.

The latest victim in a Sunday night shooting was declared dead Monday afternoon after they were sent to the hospital in critical condition. The shooting left another dead at the scene near the I-35 Frontage Road near Delmar Avenue at around 10:30 p.m. Sunday. Both deaths come after a double homicide and separate stabbing death that took place on Saturday.

No suspect description or arrest has been made for the Saturday night stabbing. The suspect for the Saturday double homicide has been identified as 31-year-old Yong Yoon Kim, who called police after shooting and killing 19-year-olds Nathan Limoge and Christopher Rivers at 11:45 a.m. in a parking lot at Burnet Road & Anderson Lane.

Kim told police that he acted in self-defense, but police have charged Kim with capital murder and booked him into the Travis County Jail with no bond due to "contrary accounts" from eyewitnesses on the scene.

Hours earlier, the first homicide of the weekend occurred when Michael Martin O'Brien was stabbed and found by Austin-Travis County EMS with life-threatening injuries on the 400 block of E. 6th St. at around 2:47 a.m. Saturday. O'Brien died due to multiple stab wounds later that morning.

Police have been told that the stabbing occurred after a fight broke out in a nearby alley. No suspect has been identified, but homicide detectives have been told by several witnesses that a white man wearing a black jacket, blue jeans and a red baseball cap fled the scene as police arrived.

“Unfortunately, this has been a rather violent weekend here in Austin that has resulted in multiple homicides having occurred over the weekend,” APD's Michael Bullock said told the media Monday.

Before this weekend, Austin had three reported homicides for 2022. Now, the number has risen to eight, higher than the total for all of January 2021. Austin had five homicides for all of January 2021 in a year that saw record-breaking homicide numbers and near-record homicide rates.

Police are asking anyone with information or videos of the incidents to email homicide.apd@austintexas.gov, call the Crime Stoppers tip line at 512-472-8477 or use the Crime Stoppers app. Tips can be anonymous, and police said those that give information that leads to an arrest for the Saturday stabbing could receive a reward of up to $1,000.
