Police need the public's help solving seven cold cases.
So far this year, there have been 31 homicides. That's down from 39 last year.
Someone has been arrested or charged in 20 of those. Four were considered justified or the suspect killed himself.
That leaves seven cases unsolved.
Police say in each case there were plenty of witnesses who they know saw something. They need those people to come forward.
"The witnesses are vital to us on any case. Without their involvement and telling us what occurred we're not going to solve these cases," said Wichita Police Lieutenant Ken Landwehr.
Anyone who has any information on these cases should call Crimestoppers at 267-2111.
