PHOENIX -- Ed Forst was murdered on June 21, 2007, but police still don't know who did it.
"It's not knowing that's the hard part," said Ed's wife, Darcy.
That's why family and friends of Forst have raised a $100,000 reward in this Silent Witness case.
Phoenix Police Sgt. Darren Burch said Forst was driving his white Denali in the area of 27th Avenue and McDowell Road when two men approached him at an AM/PM and shot him while he was still behind the wheel.
"The vehicle ended up continuing forward and crashing into a propane tank," Burch said. "There was a lot of witnesses, and we can't help but think there's people out there that know who these shooters were that just haven't come forward.
"We're hoping that somebody will remember that event because it really was dramatic, very dramatic," Burch said.
Ed and Darcy Forst had three children.
"The youngest was married two weeks before Ed died," Darcy said. "He was the proud papa, the way a father of the bride should be."
They had built a good life together in Phoenix.
"We were actually married 36 years," Darcy said. "Two days before he died was the 36th anniversary. One day after he died was the next big event: Our first granddaughter was born."
Ed was president of Sun State Builders. He'd been checking on a job site when he was killed.
"Some people might have called him a workaholic," Darcy said. "He was very driven. He worked really hard. He had a great work ethic. And he expected that of the people around him, but he never expected more than he gave himself."
Darcy said he played hard too.
"He loved to play golf and he loved to coach soccer," Darcy said. "He loved to go fishing. He and my son would fish quite a bit. We were big boating family. We had a house built on Lake Powell, and we would always go up there once a year and that was probably our favorite place to be because it was quiet -- no phones and it was just family.
"I think at times it gets harder, and I'm sorry I'm getting emotional, but when I see my little granddaughter (I know) she'll never know her grandpa and that's tough."
