Jeff Goldberg and sister, Jodi Goldberg, said they traveled from the East Coast to Las Vegas looking for answers."It would be so much easier if we knew what had happened to him," said Jodi Goldberg. "Now, we're all assuming, speculating, thinking the worst, hoping for the best."This morning, the Goldbergs met with detectives from the Las Vegas Metropolitan Police Department. The Goldbergs said police showed them the last known imagine of their 54-year-old brother.The Goldbergs said police found their brother's 2009 silver Toyota Corolla near Sahara Avenue and Las Vegas Boulevard.

"My mother's 80 years old. She needs some closure, and we need some closure.The Goldberg's quest for answers has led them to launch a media campaign, setting up a Twitter account - @findkeithg.They raised the stakes Tuesday."If anybody finds Keith or Keith's body, they will get a $5,000 reward," the family said.Keith Goldberg's family believes the reward could be key to bringing him home."I want to have a burial for him," said Jeff Goldberg.
