The family of a 77-year-old man stabbed to death in Denver last week is using a popular internet website to help get information about the elderly man's murder.

Lewis Easterday's family is turning to Craigslist to help find the person or people responsible for his death by getting the word out to as many people as they can. The hope is someone will see his picture and share information with police about what happened Tuesday night.

Officers were called to East 13th and North Marion Street around 7:30 p.m. for a report of a man bleeding. That's when they saw 77-year-old Easterday of Federal Heights with multiple stab wounds.

He was taken to Denver Health where he later died.

"He was so sweet and innocent. He didn't deserve this. He could have never done anything to make someone mad to deserve that," said Easterday's granddaughter Dariann Hansen.

His family didn't find out until three days after he died because they said authorities didn't know who he was since a wallet was not found.

"I don't have feeling. I feel horrible. I can't stop thinking about him. I miss him. That's all I think about all day, every day. I haven't smiled. I can't imagine my grandpa suffering like that," said Hansen.

Her husband Joshua Graton of Byers posted a message on Craigslist's Denver Community page on Saturday

"I can't sleep. I'm in shock. In lost and sad and hurt. Didn't even get a thanksgiving with him," the post said.

"He was a role model to me, he was my wife's grandpa, he was a husband, he was a dad, he was also a vet. He taught me a lot," said Graton.

Hansen said she spoke to her grandfather twice a day and talked to him just a few hours before he was killed. When she couldn't get ahold of him the next day, she thought he might have lost his phone.

On Friday she called her grandfather's work who told her what happened.

Crime Stoppers is offering a $2,000 reward for information in the case. Callers can remain anonymous. The number is 720-913-STOP (7867).
