Former Detective: Everybody Remains a Suspect in Mollie Tibbetts' Disappearance
Latest updates from Fox News Channel on the Iowa search.
Former homicide detective Ted Williams said that the circumstances surrounding the disappearance of Mollie Tibbetts still remain "unclear."
The 20-year-old was last seen jogging on the evening of July 18 in Brooklyn, Iowa.
A press conference with investigators on Tuesday revealed very little new information on a case that has drawn attention nationwide.
"Everybody is still a suspect in this investigation," Williams, a Fox News contributor, said Wednesday.
Tibbetts, a student at the University of Iowa, was taking care of her boyfriend's brother's dogs while the two siblings were out of town.
While it was originally speculated that something may have happened to her while jogging, evidence later suggested she returned home and did homework on her computer before vanishing.
"It's like a needle in the haystack out here," Williams said Wednesday, noting that both the boyfriend and his brother have an "airtight alibi."
Police in Pella, Iowa, said that a man who was sought for taking photos of female joggers in the area turned himself in, and that he revealed why he had done so.
Jeremy Jensen, the assistant police chief in Dubuque, Iowa, also told Fox News that there's been no indication that another man who allegedly assaulted a jogger in the area was linked to Tibbetts' disappearance.
Daniel Linskey, a former Boston police superintendent-in-chief, said on "America's Newsroom" that the lack of information provided by officials could be an indication that police are looking at new leads.
"The fact that law enforcement is not giving out a ton of details could be that they've got some type of leads they want to run down and keep a close circle around it, so as not to alert individuals that they might be looking at them or getting on a trail," he explained.
Sandra Smith noted that Tibbetts was set to go on a vacation to the Dominican Republic for the wedding of her boyfriend Dalton Jack's brother.
Linskey said police are looking into information from Tibbetts' Fitbit, since she was an avid runner, and from her cell phone, but he said it can sometimes take time to retrieve those records from providers.
In an exclusive interview with FoxNews.com reporter Cristina Corbin, Jack that he believes the doors of the home where she last stayed had been left unlocked – and he now locks his doors consistently.
“It’s Brooklyn. You don’t lock your doors,” said Jack. “We lock our doors now. Every night.”
Officials have not revealed if there was any sign of a break-in or a struggle at the house.
Jack said that early on in the search for Tibbetts, he kept calling her missing phone, hoping anyone would pick up.
"It just went straight to voicemail,” he said.
