(CNN) A man whose mother died during surgery 20 years ago is the suspect in the fatal shooting of a prominent Houston cardiologist who performed the operation, police said Wednesday. Chief Art Acevedo said the mother of Joseph James Pappas, 62, was a patient of Dr. Mark Hausknecht , who was fatally shot as he rode his bicycle to work at Houston Methodist Hospital on July 20. Houston Police released a photo of Joseph James Pappas, who is a suspect in the death of Dr. Mark Hausknecht. "It appears a 20-year-old grudge and sadly someone died," Acevedo told reporters. Acevedo said a tip came in Tuesday after surveillance video released a day before showed the suspect, whom someone said they recognized.
