Continued search for La Vista 11-year-old

Papillion, Neb. -- La Vista Police say their search for a missing 11-year-old with autism will not stop. 

Ryan Larsen was last seen on surveillance video on the afternoon of May 17th.

Since then, investigators have pulled resources from across the country to find him. Over the weekend crews from the Ashland Fire Department were out at Walnut Creek Recreation Area. 

The intense search effort led to a scaled-back salute to summer in the community.

This year's parade and fireworks were postponed.
