Parks, 51, who had worked as a Maryland Transit Authority driver for 20 years, was fatally shot after an argument with a passenger on Thursday 

The pair were arrested without incident following a three-hour standoff with police, during which neighbors were asked to shelter in place, reported CBS Baltimore. 

The shooting happened on East Fayette Street at around 10.30am as the bus Parks was driving stood empty after letting out all the passengers.

According to a statement from police, the male suspect tried to board the bus, but Parks told him that no passengers were allowed in the vehicle. 

An argument ensued, during which the suspect grabbed the driver's bag and took off, according to police. 

Parks got off the bus and gave chase, at which point the suspect shot him. 

Witness Teddy Knight recounted to Baltimore Sun seeing the victim fall over a fence and get executed by his attacker.

'He was laying there and the guy came back and shot him again,' Knight said, adding that the gunman fired multiple shots at the wounded driver as he stood over him. 

A police officer who was in the area heard the gunfire and tried to apprehend the shooter, but he could not catch him. 

Parks was pronounced dead at the scene by first responders.  

During a press briefing on Friday, Commissioner Harrison credited 'good old-fashioned detective work' and tips from the community with apprehending the suspects.  

Both Silcott and Greene were charged with murder and gun-related counts.   

Parks had worked as a bus driver for 20 years. He is survived by his three sons. 

'MDOT truly is a family. I am deeply saddened and troubled that one of our own was killed on the job this morning," Transportation Secretary Greg Slater stated. 'My sympathy goes out to the Parks family. Mr. Parks and all of our bus operators are critical to providing essential travel throughout this pandemic and every day. They deserve to be able to serve the community safely.'
