Original story below:
The Jacksonville Sheriff's Office said it will give a briefing on the search for a teen and his grandmother, who were last seen in Neptune Beach.
Logan Mott, 15, and his grandmother Kristina French, 53, may be traveling in a silver, four-door Dodge Dart with Florida tag DLLT42, according to a missing child alert by the Florida Department of Law Enforcement.
Police have been searching for Logan and his grandmother Kristina French for three days.
They were reported missing after Logan didn't show up to Sandalwood High School on Monday or Tuesday.
Action News Jax has learned French also didn't show up for work Monday or Tuesday.
Police investigated at two locations Thursday and Friday -- French's home on Nipigon Avenue South in Mayport and Seagate Avenue in Neptune Beach.
Campbell-Mott said she last spoke to Logan on Sunday and that he seemed to be in a good mood.
That is the last time anyone has spoken with Logan.
"Logan has so many friends and family that are desperate to hear from him," she said. "His father and I just want answers. Please. We are begging."
Campbell-Mott said Logan's father, Eric Mott, was on vacation with his girlfriend. They took an Uber home from the airport Wednesday after French never showed up to get them.
When they got home, the door to their Seagate Avenue home was open and the house was ransacked.
Eric Mott's guns were missing from a gun safe, Campbell-Mott said.
