The Jacksonville Sheriff's Office is asking for the public's help in locating a woman and a teen believed to be missing and endangered.
They are Logan Mott, 15, and Kristina French, 53. Police say they may be traveling in a silver, four-door Dodge Dart, Florida tag DLLT42.
A Florida Missing Child Alert has been issued for Logan by the Florida Department of Law Enforcement.
According to that alert, Logan was last seen in the 400 block of Seagate Avenue, where there is currently a heavy police presence of Jacksonville Sheriff's Office and Neptune Beach Police Department units.
Logan's mother Carrie Mott tells Action News Jax that French is Logan's grandmother. Neither she nor Logan's father have heard from them in at least 12 hours, but she said investigators are working to determine if it has actually been longer that the two have been missing.
She said she spoke to Logan on Sunday and that is the last time anyone has spoken to him. She said that Logan seemed to be in a good mood during that conversation.
Carrie Mott said Logan's father -- her ex-husband Eric Mott, who she says is a 17-year-veteran with the Jacksonville Sheriff's Office -- was on vacation with his girlfriend and arrived back into the Jacksonville area Wednesday. She said Eric Mott and his girlfriend took an Uber ride home after they were not picked up at the airport by Eric's mother.
When they arrived at the Neptune Beach home, the door was open and the home had been ransacked and Eric Mott's guns were missing out of the gun safe, Carrie Mott said. The Jacksonville Sheriff's Office was called and they are treating the home as a crime scene, Carrie Mott said.
Jacksonville police also said that firearms are missing from a home associated with Logan and French, so the car or the individuals should not be approached if encountered. Instead, people are asked to call 911 immediately.
Logan is described as having brown hair, brown eyes, is 5 feet, 9 inches tall and weighs 140 pounds. French is described as having blond hair, blue eyes and is 5 feet 4 inches tall. Carrie Mott said her son is insulin-dependent and he does not have his insulin pump.
