Investigators said they have found missing mom Michelle Parker's cell phone.
Lauren Erickson confirmed Wednesday that the iPhone 4 found by the police was indeed her sister's.
“It was an iPhone 4 with her case. She had a plaid Hurley case and it is definitely her phone. Seeing that, it gives me hope that even after so many days, you can still find something," Erickson said.
She said that even though time is passing and it seems like nothing is happening, she is hopeful that her sister's case is going to be solved.
"It's a bundle of emotions right now,” said Erickson.
It's not clear where Parker's phone was found or what condition it was in, but officials said finding it would be a major step forward in the investigation.
“It obviously means something. Who knows what's in that phone, her last text messages. I hope it leads to something. It has to,” Erickson said.
Parker was last seen Nov. 17, the same day that an episode of "The People's Court" aired that featured a case between her and suspect Dale Smith. Smith is Parker's ex-fiance and the father of her twins.
Smith's mother, Tamara Smith, spent about 30 minutes this week answering questions under oath after being issued an investigative subpoena by the state attorney's office.
Richard Hornsby, Tamara Smith's attorney, said his client was cooperative and had nothing to hide.
A former prosecutor, Jeff Dean, said it could be a tactic to keep the pressure on Dale Smith.
"A lot of the questions will be open-ended. 'Tell me about that day. When did you talk to your son? When you saw him, how did he look? What was his demeanor?'" Dean said.
Meanwhile, Parker's family has expanded their search. They passed out fliers in Daytona Beach on Tuesday after her family said a tip was received by Crimeline that the missing mother was seen in the area.
