NORTH MIAMI, Fla. -- By NBC 6's Hetal Gandhi

"He was not just a grand master in the studio, but he was a father figure," said Ricky Do. "He was a loving husband, everything that a family should be."

Despite everything he gave, the life of 62-year-old Young Soo Do was taken away on Nov. 10, 2007, outside his North Miami studio.

"Classes were in session at the karate school and they were being instructed by Ricky Do and his sister. They heard the gunshots," said Sgt. Scott D. Croye with North Miami police.

For the first time, police have released the 911 call made by Do's daughter.

Dispatcher: "Do you see the person or know who got...?
Caller: "Yes, it's my father. He's laying on the ground."
Dispatcher: "OK, the person that did the shooting, where is that person right now?"
Caller: "I have no idea, we just heard the shots."
Dispatcher: "OK, only one shot?"
Caller: "No, it was like three or four."

"When he was looking up at me he said, 'He had a mustache, mustache,'" said Ricky Do, the victim's son.

It was the only clue about his killer that Master Do would live to tell. The other victim, Leclerc Prosper, survived but provided little to help police solve the case.

Prosper was using his yellow van to wash Master Do's black Cadillac when a gunman approached them in a car.

"The possible motive we're looking into in this case is a robbery that went bad," said Croye. "After the shooting the subject ran down this alley way."

The getaway car -- a Mercedes -- was caught on surveillance video.

"There's almost 3,000 vehicles that match that general description in Dade and Broward County," Croye said.

One dead end in a case that was personal for police -- many officers were trained by Master Do.

"He treated me like a son," said Peter Cruz of North Miami police. "He introduced me as a son and he accepted me as a son."

"The fact that we have no information at this time to follow up or very limited information at this time to follow up is distressing to me," Croye said. "I want to solve this case."

The family is moving forward, opening two new studios and remembering Master Do's great lessons even in dealing with his death.

"Anger is not a good thing," Ricky Do said. "Forgiveness from the heart is better and that's how we should all live our lives."

A reward of up to $57,000 is being offered for information leading to an arrest in this case. Call Miami-Dade Crime Stoppers at 305-471-TIPS.
