JACKSONVILLE, Fla. – As the search for the body of 21-month-old Lonzie Barton continues, and as police say they are continuing to build a murder case against Ruben Ebron, the man last seen with the toddler, the timeline of events surrounding the toddler's disappearance has continued to grow.

Police are now questioning whether Ebron was alone in his scheme to dispose of the toddler, ditch his car and allege a carjacking, or if someone else knew about what police are calling a scheme to cover up a murder.

Over the past 12 days, the case has gone from a frantic search to find Lonzie, to a murder investigation focusing solely on Ebron, to the possibility of other people being involved in Lonzie's disappearance.

According to John Fleming, the day before Lonzie was reported missing, Fleming noticed Ebron's orange Honda Civic parked along his street, right in front of his house.

"It's a bright orange Honda Civic, kind of stands out in the crowd," Fleming said.

That was just 10 hours before the car was reported stolen by Ebron, with Lonzie inside, a child who police believe was murdered by the 32-year-old.

Fleming said Jacksonville Sheriff's Office detectives told him that Ebron likely parked the car in front of his house the day before calling 911 because Ebron was rehearsing the cover-up to the crime.

"They said that he might be trying to time his actions, running from here to his apartment on Old Kings, because it's a straight shot behind these houses over here on Sierra Madre, all the way up to Ravenwood. Even an old fat guy like me, it would take about four to five minutes to run to the Ravenwood Apartments," Fleming said.

Police said that grainy home surveillance footage captured just 10 hours later, shows Ebron going through with his scheme, first ditching the car, and then sprinting home before dialing 911.

After 11 days of searching more than 40 square miles of land and 61 bodies of water, police think someone else besides Ebron may know what happened to the little boy, maybe even his mother, Lonna Lauramore.

"She's been receptive to our questions. Without going into great detail, she's been there when we needed her. She's had a lot to deal with. But if there is somebody --that includes Lonna -- associated with this -- that we can prove had something to do with this --, they will go to jail," JSO Chief Tom Hackney said.

JSO officers won't confirm if they have surveillance video of Ebron running along the same street while rehearsing the crime the day before. But neighbors like Fleming said it would only make sense that police have more evidence than they're sharing with the public. He said as time goes on he suspects more than one person may know where Lonzie is.

"It wasn't a spur of the moment thing, otherwise he wouldn't be over here almost 10 hours before the car was dropped off the next morning," Fleming said.

Lonzie's family continues to search for missing toddler

While Ebron remains in jail on child neglect charges, and police continue to say he's lying and won't tell them what happened to Lonzie, the toddler's relatives are out on the street, armed with hundreds of flyers, which local printing companies donated, hoping that showing Lonzie's picture to everyone will help get the answers that have been absent so far.

"I have been praying a lot about it. Just trying to do what I can to keep his face out there," Sabra Rhue, Lonzie's relative, said. "Somebody had to see something."

Rhue drove from Baker County Tuesday to pass out flyers near where Lonzie disappeared.

"I have grandchildren of my own and I cannot imagine what a 21-month-old could do to a grown person," Rhue said. "He is running. I mean if you park your car and you are running, you have something to hide. So he needs to speak up and tell where this child is."

Until then, Lonzie's loved ones said they're going to keep working the community, and praying for closure.

"We are not giving up hope, never," Rhue said.

News4Jax reached out to Ebron, but as he's done every other day, he declined an interview. One of Ebron's friends said she's still confident that he would have never intentionally hurt Lonzie, but she wants answers, too.

Anyone with information is asked to contact the Jacksonville Sheriff's Office or Crime Stoppers at 866-845-TIPS. Tipsters can remain anonymous and be eligible for a reward of $13,200 leading to the recovery of Lonzie.
