Acevedo has said Pappas might have been seeking revenge for his mother, who died on the doctor's operating table more than 20 years ago, in April 1997. Pappas reportedly committed suicide Friday as police officers confronted him.
Chief Acevedo thinks Pappas made the gesture in hopes the parks employee would come closer.
The employee called police several times to provide updates on Pappas' location - allowing an officer to move in on him near the intersection of Bob White Drive and Imogene Street. He said the last anyone had heard from Pappas was in a Tuesday morning text message in which Pappas wrote that he was going to kill himself.
While each homicide is a tragedy for our community, I am thankful that last year's Houston homicide count fell to a three-year low and that Chief Acevedo and his staff are using preventive approaches created to reduce the count even further.
"I am thankful today for quite a few things, No. 1 that we will end this week with a great sense of relief in the City of Houston, the Texas Medical Center", the chief said.
Upon following up to the call, police found Pappas, 62, wearing a bullet-proof vest.
- Houston police have identified the suspect in the murder of a well-known Houston cardiologist.
"The potential threat to the City from an accused murderer considered armed and risky is now over, closing another chapter of this horrific tragedy", Turner said. Media's role in keeping the public informed is also acknowledged.

The crewed test flights were also supposed to take place this year - Boeing's in November and SpaceX's in December. Separately, SpaceX's Crew Dragon spacecraft for Demo-1 arrived to the Cape in July for final processing.
Friends and family have described Hausknecht as a humble and generous man who was adored by his patients, volunteered in his community and cared about the environment. Hausknecht's brutal murder rocked the Houston community, and Pappas was the main suspect.
The city had been on edge since Dr. Hausknecht's shocking murder.
The friend, Jeanette Spencer, said Pappas told her the next day over the phone that he deeded the house to her because he had a terminal illness.
The chief didn't say which homes Pappas visited, when he visited them, what he did there, or whether anyone else was present at the time.
Pappas worked for 30 years as a constable in Harris County, as a peace officer and reserve officer.
The day before gunning down the cardiologist, Pappas transferred the deed of his home in a rush to a woman who lives in Ohio.
