ST. LOUIS – At least one person was killed Monday evening in a mass shooting in Downtown St. Louis that left three others wounded.

The shooting happened at 20th and St. Charles streets, one block south of Washington Avenue, at about 8:40 p.m. That’s about a tenth of a mile from St. Louis Metropolitan Police Headquarters.

The victims were attending a candlelight vigil for Demetrise Thomas, 27, who was shot and killed at basically the same location Monday just before 1:00 a.m. FOX 2’s Nissan Rogue Runner reporter Jason Maxwell was at the scene.

Police sources at the Monday night scene initially reported five people had been shot. However, Chief John Hayden later clarified and said there were four shooting victims: two males and two females. The one victim who died was male. He was rushed to a hospital where he was pronounced dead. That man was in his 20s.

Hayden said a few dozen people were gathered for the vigil when a dark-colored SUV drove past and someone in the vehicle opened fire at the crowd. Children at the vigil fled at the sound of gunfire and ran to Union Station for safety.

The extent of the other victims’ injuries is unknown at this time.

Hayden said officers are now searching for suspects.

The investigation remains ongoing.

Public Safety Director Dan Isom released a statement on the recent violence in St. Louis City Tuesday morning.

Every life lost to gun violence is a tragedy, and our city mourns last night’s attack on those who came together for a peaceful vigil. One homicide is one too many, and any efforts must take into account the needs of these communities and address root causes of crime – poverty, housing instability, and more – across St. Louis. 

There’s no quick fix to address crime in our neighborhoods, but we are dedicated to providing the resources necessary to make our downtown region and all of St. Louis a safer place for every resident.

Isom said.

Hayden will address these shootings along with other developments in multiple connected homicides in north St. Louis City and St. Louis County.
