BERKELEY, Mo. — St. Louis County prosecutors have charged a Ferguson man with two counts of murder after they say he fired shots into a Metro bus Monday afternoon, killing two people inside along Airport Road in Berkeley.

The Major Case Squad of Greater St. Louis announced late Monday night that it had taken a suspect into custody.

On Tuesday, authorities charged Anthony Laron Frazier with two counts of first degree murder, four counts of armed criminal action, robbery, and for being a felon in possession of a handgun.

Frazier was previously convicted of vehicle tampering and was wanted in connection with stealing cases out of St. Charles and Chesterfield.

According to court documents, Frazier confessed to a carjacking in Bellefontaine Neighbors that took place prior to the shooting. The probable cause statement filed by police said Frazier was caught on bus surveillance video firing shots into the Metro bus in the area of Jefferson and Airport Road at around 2:30 p.m. Monday. Police say Frazier admitted to targeting Jorge Andres Cantor Pinzon, 37, of Maryland Heights, because “he didn’t like the way he looked at him”. Frazier did not know Cantor Pinzon, police say, and also did not know Jaron Jackson-Craig, 34, of Olivette, who also died from his injuries.

Police say Frazier came aboard the bus and fired more shots before fleeing the scene in the vehicle involved in the earlier carjacking.

Frazier is being held without bond. 

"This was a heinous and vile act. It is something that is very discouraging not only for our mode of transportation but our entire region. Unfortunately we see this all too often in the region, the profound violent crime crisis that continues to play out," said Kevin Scott, General Manager of Security for Bi-State Development, which operates MetroBus and MetroLink.

"We have blanketed our system, our units of transportation, our buses our trains, our properties with a very advanced close circuit model that is viewed in real time," he added. "If you use metro transit to conduct or cause peril to someone or as a mode of transportation to cause peril to someone, we will exhaust all of our options to ensure that you’re brought to justice."

Berkeley Police Chief Art Jackson called the case "horrendous", unlike any he'd seen in thirty years of law enforcement.
