The biological parents of Sebastian Rogers met with officials from the Tennessee Bureau of Investigation and investigators from the Sumner County Sheriff's Office on Thursday, over a month after he vanished from his own home. 

Sumner County Sheriff Sonny Weatherford confirmed to WSMV4 that the meeting took place, but refrained from disclosing any specifics regarding the purpose or the lead participant behind the gathering. 

On Mar. 8, authorities searched a Kentucky landfill as part of efforts to uncover evidence related to Sebastian's disappearance. 

Despite their efforts, no leads or evidence of Rogers' whereabouts emerged from the search.

The Sumner County Sheriff's Office explained that the decision to search the landfill was based on "ongoing investigative efforts and information gathered" during the search for Rogers.

Rogers, who is 15-years-old and has autism, has been missing since Feb. 26. He was last seen by his mother on the night of Feb. 25 when she had put him to bed.

"When I told him to go to bed, he was like, 'I love you, mom, I love you puppies,' and he went to bed; and I went to bed around midnight, and everything seemed fine, and when I went to wake him up for school, that's when I couldn't find him," Sebastian's mom, Katie Proudfoot, explained to the station earlier this week.

"He wasn't in his room." 

The TBI has affirmed that there are no signs of foul play in Sebastian's disappearance, but there is also no evidence definitively ruling it out.

"While we had hoped for a different outcome, our commitment to finding Sebastian remains unwavering," Sumner County Sheriff Sonny Weatherford said in a previous statement. 

"We will continue to explore all available avenues and resources to bring closure to this case and provide answers to Sebastian's family and loved ones." 

An AMBER Alert was activated for the 15-year-old boy.

Anyone with information on his whereabouts is urged to contact the Sumner County Sheriff's Office at 615-451-3838 or TBI at 1-800-TBI-FIND.
