Liberty County homicide detectives have identified several "persons of interest" in the mysterious disappearance of Dennis Rogers.

Rogers has been missing since Thursday, March 8.

The search for the Plum Grove man was suspended Tuesday and deputies began calling the case a "criminal matter."

Evans said someone came forward Tuesday with information they’d learned from a Facebook chat session. The chat involved a conversation overheard in a Harris County bar implicating several people who allegedly found Rogers alive and may have harmed him, according to Capt. Rex Evans with the Liberty County Sheriff’s Office. Detectives questioned two people late Tuesday and into the night, Evans said. Others will be brought in for questioning Wednesday. This is an attempt to qualify the information received.

Evans said they’ve also subpoenaed Rogers’ cell phone records.

Rogers, 54, had an accident several years ago that left him with memory problems, family members said.

He made several calls for help after he got lost Thursday, but then his cell phone battery went dead. He hasn’t been heard from since 1:30 a.m. Friday.

Rogers told Liberty County 911 dispatchers, "Uh today, I uh, I went walking and went too far and now, uh I’m somewhat lost."

"So you don’t know where you’re at?" the dispatcher asked.

"Uh, I’m close to my home," he said.

Dennis Rogers is affected with short term memory loss and does not  have a mental capacity as it has been reported in the past. He remembers people, he remembers the past it’s just immediate things he forgets at times.

Despite rainy weather, volunteers spent several days searching thousands of acres of sparsely populated forests and farmland near Plum Grove, looking for Rogers.

Tuesday afternoon, deputies rounded up dozens of volunteers and told them to go home.

Detectives with the Liberty County Sheriff’s Office are still actively investigating the case as of 5 p.m. Wednesday.
