REDDING -- Redding mom Sherri Papini went missing 16 days ago. The search is on to find the 34-year-old who disappeared while jogging.
The Shasta County Sheriff's Office, Redding Police Department and FBI are working together on this missing persons case. Investigators call it a top priority. They're looking at cell phone records, emails and social media for clues.
"She's just that amazing friend that you can always call she's always there," said Papini's childhood friend, Melissa King, who moved from Redding to Roseville.
Shasta County Sheriff's investigators said they've received hundreds of tips, but so far there's no sign of the 34-year-old.
"It's like she vanished into thin air," King said. "She's just gone."
Detectives ruled out Papini's husband as a possible suspect.
The case is listed as suspicious and investigators believe Papini is at risk. They're still trying to figure out if she left on her own or was kidnapped.
"She loves her husband, she's so devoted to him she would never leave him; she would never leave her kids," King said.
A $50,000 reward is being offered by family and Shasta County for information leading to the whereabouts of Sherri.
An anonymous Redding visitor has also created a website where he pledges to give a cash ransom no questions asked for Sherri's immediate release.
