Lt. Billy Adcox with Tonganoxie police said law enforcement officials continue to work on the case of Luke Stevens, 27, who last was seen at his Tonganoxie home May 26. Earlier reports stated that his 1983 dark blue Chevrolet truck was found a week later at Longview Lake, which is near south Kansas City, Mo., in Jackson County. His mother, Joyce Stevens, said Tuesday that his truck first was discovered at the lake May 27.

The family released Stevens’ two cell phones to Tonganoxie police, but Adcox said analysis of the phone’s call history was inconclusive.

A $1,000 reward is being offered to anyone with information that leads to Luke Stevens’ whereabouts. He is 6-5 and weighs roughly 250 pounds. Anyone with information should contact Tonganoxie police at (913) 845-2311.
