LINCOLN, Neb. -- Wednesday will mark one week since friends and family last heard from Sydney Loofe. Police say her phone is now off, and it was last pinged in Wilber.
"As the hours passed, we knew something was wrong," Leah Shaw said.
It's typically during this time when friends or family like Leah jump start the first step in a missing persons investigation.
Chief Jeff Bliemeister at the Lincoln Police Department said, "We come in. We respond to the call...we complete reports."
In some situations -- like juveniles -- they are entered into a national database to speed up the process. Then two questions are asked.
"When do we go public? How much information do we provide the public as to enhance the liklihood of finding them in a rapid way?" Chief Bliemeister said.
He also said it's difficult to determine whether a missing person is in danger, but police analyze patterns of activity, the person's future plans, where and who saw them last -- and in some circumstances -- search of residences or vehicles.
"All of us leave a digital footprint, and that can come in many facets...but it's certainly become a big part of investigative process," Chief Bliemeister said.
Officers also rely on tips from people who call in from the community, which could be the difference of bringing a missing person home.
Chief Bliemeister said, "Every single inquiry that's made with Lincoln Police Department...or bit of information that's shared with us...we are following up on it...to try to conclusively prove or disprove that it's relevent to the ongoing investigation."
