Police detectives are aggressively searching for the suspect who allegedly shot and killed a passenger on a VIA bus in the 1200 block of North Main Street between Cypress and Poplar streets Tuesday afternoon.

Sgt. Javier Salazar, a spokesperson for the local police department, said an unidentified man accompanied by a woman boarded the 90 bus a little before 2:30 p. m. The suspect was eager to start confrontations with other passengers and started making eye contacts with them.

A few minutes later, the suspect approached a man and angrily asked what he was looking at. When the man replied that he was not looking at anything, the suspect fired several shots at him.

After shooting the victim, the suspect demanded the bus driver to stop the bus. The driver complied and the suspect and his companion got off the bus.

The victim, who was thought to be in his 20s, was pronounced dead at the scene. Police didn't reveal the name of the victim yet.

Charlie Gonzalez, senior vice president of public engagement at VIA, said the agency prioritized passenger safety and the shooting incident appeared to be a freak incident.

Extending condolences to the family of the victim, he said, "We have 44 million boardings a year, we cover 1,200 miles of roadway. As tragic as this is, as terrible, as horrific as it is, you have to have a frame of reference."

The suspect has been described as a 5-feet-5-inch tall man, wearing a gray Dallas Cowboys hoodie or shirt with blue lettering. The woman who accompanied the suspect is said to be heavy-set. She was wearing a pink hoodie at the time of the fatal incident.
