WICHITA, Kansas -- On September 7, 2011, Tim McGuigan's son found his father shot to death.
The victim was a family man and a huge supporter of the Wichita community. Investigators have no motive, tips or leads in the case.
But family and friends of McGuigan, as well as police, hope an extra large reward will bring out someone who knows something.
"We've interviewed 40-50 people and no one seems to know why or how this occurred," said Lieutenant Todd Ojile, Wichita Police Department's Homicide Unit.
The questions remain without answers.
In the home he'd lived in for just a month, in the 2500 block of N. Woodridge, between the hours of 8 p.m. on September 6th and 10 a.m. September 7th, someone shot and killed Tim McGuigan.
"It's possible he knew his assailant and let them in," says Lieutenant Ojile.
Police found the door to the home locked. Nothing was taken.
A shocking mystery for those who knew and loved McGuigan.
"A great joy in life is when we're lucky to have a good, good friend. Tim was a fantastic father, wonderful brother, he was the ideal true friend, a friend to many of us," says Dave Dahl.
Another friend Brian Frye says, "Tim is missed by many of us and while we know that finding his killer won't bring him back we believe it will make this community safer and better for all Wichitans."
To help police make an arrest in the case, donations from Wagonmasters, Crime Stoppers and friends and family have led to a more than $20,000 dollar reward for information that leads to the person who killed McGuigan.
"We were just stuck with there not being anything going on with the case that seemed to be leading to anything, so we came up with the idea, my mom, my sister, to post some reward money," says McGuigan's son J.J.
"Why it happens to anyone is unclear," said Dahl. "Why it would happen to Tim McGuigan makes no sense at all to me."
The more than $20,000 dollar reward is the largest in Wichita's history.
For this homicide and some other unsolved homicides, Crime Stoppers is doubling its portion of the reward to $2,000 for information that leads to cracking the case.
