Federal agents are continuing their investigation into a large boulder on a Phoenix (Arizona, USA) man's front yard saying the rock is an artifact stolen from the Lake Pleasant area.  Six weeks ago, agents took the rock, which has drawings by ancient people. Tuesday, federal law enforcement officers returned to search the house. The rock owner, Eric Zoller, 46, said someone gave him the rock.
     The agents did not arrest Zoller, but Bob Ruiz, special agent for the Bureau of Land Management, said the agency is investigating a violation of the Archaeological Resources Protection Act of 1979. Federal law bars people from removing or damaging archaeological resources on public or Indian lands.
