ALLENTOWN, Pa. -

A grieving family is sharing new details of an unsolved murder in hopes of getting a killer in custody.

Michael Sikler, 34, was murdered inside his own home on quiet stretch of North Ott Street in Allentown last December.

Sikler's mother, Bernadette Kline, found his body wrapped inside a blanket. She said there were signs of a struggle.

"We came in and he was dead in the garage," said Kline. "We had pulled the blanket off of him and I could see the back -- his back and the back of his legs ... and he looked like he had a smile on his face."

An autopsy revealed Sikler was stabbed and struck with a blunt object. His family said they never saw an obvious murder weapon.

In December, police and Lehigh Co. District Attorney Jim Martin said they were confident the killer targeted Sikler and his home.

"I feel like he was definitely targeted," said Sikler's brother, Brian. "The way it all came about, the way it all happened."

"I don't know if you want to say 'targeted,' but somebody definitely knew something," said Sikler's sister, Linda Douglas.

This week, Sikler's family announced a five thousand dollar reward. His home of five years, once a crime scene, has now become an unlikely memorial to the man who went by "Mick" and loved the fishing and the outdoors.

"It's very uneasy, just knowing this is where he took his last breath and everything," said Brian Sikler.

"Our family is hurting," added Kline. "We need to know -- I need to know -- why."

Police have been very tight-lipped about their investigation. His family believes police are still doing DNA analysis on evidence collected in the garage.

Michael Sikler had spent time in jail on drug charges in the past, but authorities won't say if they think there's a connection. Sikler's family said he never mentioned any type of fears or threats before he was killed.
