Surveillance video shows Danelo Cavalcante, 34, who escaped from Pennsylvania prison last week, at popular botanical gardens

Authorities have moved and expanded the search area for a convicted murderer who escaped from a suburban Philadelphia prison last week, after he was spotted on a trail camera at one of the nation's premier botanical gardens.

Danelo Cavalcante, 34, has been spotted five times since he escaped on Thursday from the Chester state prison. The most recent sighting came on Monday night at Longwood Gardens, where surveillance video captured him walking through the area with a duffel bag, backpack and hooded sweatshirt.
