More than 1 suspect not ruled out, sheriff's office says
Investigators are not ruling out the possibility that more than one person may have been involved in Nancy Guthrie's abduction, the Pima County Sheriff's Department said Friday.
The sheriff's department said it also continues to seek information to help identify the man captured on Nancy Guthrie's doorbell video, and that investigators are reviewing surveillance video submitted by her neighbors.
Man detained last week identified
A lawyer representing a convicted felon said his client and his client’s mother were briefly detained as part of the Nancy Guthrie investigation.
Luke Daley, 37, and his mother, who is 77, were detained and had their house searched on Feb. 13, according to his lawyer, Chris Scileppi. Their home is about 2 miles from Guthrie’s.
Chris Scileppi confirmed Daley -- who has served time in state prison on drug-related charge -- was the target of the operation by the FBI and Pima County Sheriff’s Department but reiterated neither Daley nor his mother were arrested and said they have no link to Guthrie.
“Like the entire Tucson community, both Mr. Daley and his mother are hopeful that Nancy will be returned to her family unharmed,” Scileppi said in a statement.
Daley was the second person detained for questioning and released after a deliveryman who identified himself as Carlos was stopped earlier in the investigation. ABC News has previously reported investigators are leaning away from both men as possible suspects.
