LOUISVILLE, Ky. (WDRB) -- On the day a Louisville murder victim would have turned 32, his mother speaks out for any information that might solve the crime.

Dennis Holland was shot and killed in July of last year at Taylor Blvd and Central. His family members purchased a billboard near the site of the crime to advertise a 10-thousand dollar reward, in hopes that someone with information would come forward.

So far, no one has.

"I just ask please break your code of silence," Holland's mother Donna Linker said, "because whether you pulled the trigger or not on any of the murders you are just as guilty."

The week Dennis Holland was killed, LMPD says six homicides took place in four days. Holland being one of them.

If you have any information on this crime or any others call LMPD at 574-LMPD.
