According to the chief, a city parks board employee who'd been checking for graffiti in the area near the Jewish Community Center came across a man in the area not far from Pappas's home in Westbury and approached him. As he did, Pappas walked away and the employee yelled after him "Sorry, I thought you were a graffiti vandal," Acevedo said.
The employee found a wallet belonging to Pappas that had been thrown on the ground and contacted the Houston police.
The employee repeatedly called police with the whereabouts of Pappas ( Acevedo said they were slowed when the first address turned out to be incorrect). The first officer on the scene confronted Pappas, who was wearing a bulletproof vest under his shirt, and asked him to show him his hands.
Pappas refused to do so and when a second office arrived, Pappas shot himself, police said.
Acevedo referred to the tension there has been in the Texas Medical Center community since the fatal shooting of Hausknecht two weeks ago. The doctor was shot while riding his bicycle in the Medical Center area. The motive for the shooting is believed to be the fact that Pappas' mother died while under the cardiologist's care more than 20 years ago.
