Two decades after a man was shot to death on Honolulu's waterfront, the case is heating up.
Tuesday marks 20 years since David Walden's death.
"When they told me the news, I screamed so loud and I just collapsed on the floor. I was devastated," said Walden's daughter, Angela Whitworth.
She said it happened two weeks after her 15th birthday. "It breaks my heart when my kids hear about my dad and they tell me that they feel sorry for me that my dad died. I was so young it was heartbreaking," she said.
On April 6, 1994, Walden, a movie truck driver, was taking in equipment at Pier 24 in Honolulu. At that moment, witnesses reported hearing gunshots and saw two people on motorcycles drive off. Walden was found shot several times in the head.
"(It) looks like it was a planned homicide," said Honolulu Police Capt. Richard Schaab. "Those two people had full helmets on, with shields (over their faces) and full long-sleeve attire."
For many years, detectives suspected the killing was sparked by a turf war between movie truck companies.
In 1999, former KITV investigative reporter Jim Dooley profiled people whom agents believed had ties to the case as witnesses. They were people, police suspect, who knew details about what happened or those who were prominent figures in that turf war.
Police now say they have "persons of interest" in the case, but no arrests have been made.
"We understand they want closure. We want closure," Schaab said.
Angela and her brother, James Walden, who live in Missouri, said until this day, people are still contacting them with bits and pieces and tips and names related to the case.
It's not information they're willing to share yet, but it has them believing, once again, that the case can be solved.
"We thought we had this solved 20 years ago and there still has been no justice," James Walden said.
"There are people out there, that know, that can help us solve this crime," said Whitworth.
Honolulu police assigned a detective to the case about a year ago, but they are not discussing new evidence.
Walden's family has started a Facebook page called Justice for David Walden.
