Salt Lake City ? Police have administered polygraph tests to a number of people both inside and outside 14-year-old Elizabeth Smart’s family, authorities said Thursday.

Sixteen days into the investigation of Elizabeth’s apparent abduction, police say they still had no suspect. The girl reportedly was taken from her bedroom at gunpoint in the early hours of June 5.

Police Chief Rick Dinse wouldn’t elaborate on what the polygraph tests found.

He also said police have searched the hard drives of 12 computers, and “We have found nothing on computers that creates a nexus (link) to this crime.” Police said they examined computers owned by the immediate family and others.

FBI agents are looking at other kidnappings, including two teens taken from the same apartment complex in Oregon and one in Idaho Falls, Idaho, that ended with the suspect’s suicide, said special agent Dan Roberts. The one in Idaho Falls, which is about 190 miles from Salt Lake City, took place the same morning as the abduction of Elizabeth.

In addition, police said they were aware of one e-mail ransom note, but Dinse said they considered it a hoax.
