Man accused of killing George W Bush's cardiologist may have been seeking revenge, police say

The suspect, Joseph James Pappas, 'should be considered armed, dangerous and possibly suicidal', say authorities

A man suspected of killing one of former president George HW Bush’s doctors may have been seeking revenge for his mother, who died on the doctor’s operating table more than 20 years ago, authorities said on Wednesday.

Joseph James Pappas, 62, should be considered armed, dangerous and possibly suicidal, Houston police chief Art Acevedo told a news conference.

“There was a lot of planning that went into this. There was a lot of planning and, sadly, some skill,” Mr Acevedo said of the 20 July attack on Dr Mark Hausknecht. Dr Hausknecht was gunned down while riding his bike to work at Houston Methodist Hospital, which is part of the busy Texas Medical Centre. Authorities say the shooter rode past Mr Hausknecht before turning around and firing.

A tip on Tuesday led police to suspect Mr Pappas, the chief said, though he did not elaborate as to the nature of the tip.

Mr Acevedo said Mr Pappas hadn’t been seen in 36 to 48 hours. He said the last anyone had heard from Mr Pappas was in a Tuesday morning text message in which Mr Pappas wrote that he was going to kill himself.

Mr Acevedo said police searched his home at 4am on Wednesday and found evidence that ties Mr Pappas to the killing, but he declined to elaborate as to the nature of the evidence.

The chief said Mr Pappas is very fit, and that he’s likely getting around on his 10-speed bicycle, which he rides “extensively and almost exclusively”.

Friends and family have described Mr Hausknecht as a humble and generous man who was adored by his patients, volunteered in his community and cared about the environment.

Mr Hausknecht was also an avid cyclist and rode his bike to work each morning, as he lived less than 2 miles (3.2 km) from his office.

In 2000, Mr Hausknecht treated Mr Bush for an irregular heartbeat after the ex-president complained about lightheadedness.

Neighbour Jim Herd said he has known Mr Pappas all of his life, having attended the same high school and church as him.

Mr Herd described Mr Pappas as a nice, quiet man who kept to himself and had few close friends.

“He was a loner,” he said.

Mr Pappas’ house, in which no one was found Wednesday, is in an older, established neighbourhood in southwest Houston. Most of the homes are single-story ranch homes with neatly manicured lawns.

Indeed, Mr Pappas kept a neat yard, Mr Herd said, and he saw Mr Pappas mowing his lawn a week after the doctor was slain.

The house was home to Mr Pappas’s parents and their family from the time Mr Pappas was born, Mr Herd said, adding that Mr Pappas inherited the house after his father’s death about 10 years ago. Since then, Mr Pappas had lived there alone.

Mr Herd said he and Mr Pappas had few words but would wave at each other in passing – the last time on Saturday, when Mr Pappas waved at him as Mr Herd washed his car in his driveway.

Mr Herd said he does not remember ever hearing Mr Pappas speak bitterly about his mother’s death or place blame for it. But “it hit him hard,” he said, and Mr Pappas stopped attending church for a long time afterward.

After police released photos from surveillance video of the suspect in Mr Hausknecht’s slaying, Mr Herd said he thought it resembled Mr Pappas but brushed the notion aside.

“Never in a million years would I have thought it was him,” he said.
