HOUSTON – A flag and a cross sit in Deputy Greenwood's parking spot on a peaceful day much different from what police say happened Monday.
Hundreds of people gathered at that spot on Tuesday to remember Clint Greenwood.
"It's surreal. Clint was the first one here every morning, usually bringing breakfast," Chief Clerk Pct 3. Constables Office Jill Harrison said.
On Tuesday, Harrison created a memorial in Greenwood's parking spot while the county courthouse has reopened.
"We have a job to do and we would not be doing right by Clint if we didn't get in there and do our jobs," Harrison said.
Employees and community members mourn the loss of Greenwood.

"They're just out here protecting us and doing their jobs and it's pretty tragic," community member Shane Morgan said.
The city of Baytown held a vigil at the courthouse Tuesday night.
"He gave his life protecting and serving us, the least we can do is come out and show some respect to him," Travis Scroggins said. "I just hope they catch the guy that did this so they can bring down a good Texas justice on him and get him off the streets so he can't harm anybody else."
The memorial marks the same place investigators said someone gunned down Greenwood Monday morning. The killer is still on the run, but investigators believe that person is seen in surveillance footage.
Investigators said the footage shows a dark-colored car, likely a small SUV speeding away.
Police are also looking for a white or Hispanic man, 6 feet to 6 feet 3 inches, with short hair and a medium to stocky build. He may have been wearing a dark jacket with a patch on a sleeve.
BACK THE BLUE CONVOY

A #BackTheBlue convoy met around 5:30 p.m. Tuesday at the Bucees in Baytown.
They left around 6 p.m.
Everyone was welcome to join the road -- with, or without, flags.
"We're here to fly our flags and convoy," said Dylan Davidson. "The more the merrier."
The convoy was expected to have police escorts, but still advised all who joined to obey traffic laws and to keep hazard lights on at all times.
People came out to show support for Greenwood, and all enforcers of the law.
"To show support in general to the police department and how much we're thankful for their service," said Edwin Aguilera.
