NIAGARA FALLS — Family and friends of John Adams, a Seventh Street man who has been missing since July 4, have spread their net wider as they continue the search for him, and now are offering a $1,500 reward for information leading to his whereabouts.

One Niagara welcome center owner Frank Parlato confirmed Monday that he will offer the reward for information that helps in the discovery of the 67-year-old Adams, who worked in the One Niagara building, near the Rainbow Bridge, as a cleaner.

Adams had been at work the night he went missing, just after 10. He never punched out at the end of his shift and never returned to his home in the 400 block of Seventh Street that night.

Detective Lt. Michael Trane has said police do not suspect foul play, but that tips they have received so far have not panned out.

Adams' sister, Evie Shepherd, said her brother likes to work odd jobs, and that he bikes everywhere but his bike is still at home.

The family has fanned out of the Falls to post more missing person signs.

"We've even put up signs in Lockport," Shepherd said.

Adams is 5-foot-7-inch tall and weighs about 145 pounds. He has gray hair and is missing his left index finger.

Parlato said Adams has worked for him off and on since the two met in 2005.

"Someone may know something. It's almost inconceivable to me that he would have just wandered off on a lark and gone on an adventure and disappeared," Parlato said.

Anyone with information should contact the Niagara Falls Police Department at 286-4711.
