Police hope this will help them identify someone who might have been in the house without the Smarts' knowledge.
"We are not using this to implicate anybody," Salt Lake City police spokesman Sgt. Fred Louis said. "We just want to verify who was in the home that morning."
Police told The Associated Press that five of the eight male neighbors who were asked to provide their fingerprints did so on Monday. The other three were out of town and said they would give police their prints when they return, the news agency reported.
Police continued to deny reports there are plans to ask neighbors to submit blood or DNA samples, though they say that could happen as the investigation develops.
So it looks like 11 people? men.
