NEWPORT-Officers with the Tennessee Bureau of Investigation, Cocke County Sheriff's Department, and Newport Police Department conducted two more searches on Wednesday for any clues to missing teenager Megan Maxwell's whereabouts.

The searches that took place "east of town," Newport Police Chief Maurice Shults said, "didn't yield anything."

They were conducted based on some "information" officers had received, but which the police chief downplayed as "not really a lead."

Shults said Wednesday's searches were conducted "right behind each other." He said he was present when they began, but did not stay for the entire length of the searches.

William Brownlow Marsh, Assistant District Attorney General, said Tuesday, "We're not at a standstill" in the investigation of the possible murder case.

Maxwell, 19, disappeared early Sunday morning on April 26, nearly two months ago. She apparently has not been heard from since.

Maxwell's Mitsubishi Eclipse was discovered burned up the morning she disappeared.

Asked if perhaps he thought Maxwell had run away and kept silent since then, Brownlow said, "That's always a possibility until we find her."

Meanwhile, all news media inquiries have been directed to Brownlow to handle, including those addressed to the lead investigator in the case, Detective Derrick Woods of the Cocke County Sheriff's Department.

"No one has reported seeing her, period," Brownlow said.

Talk of sightings of Maxwell "are just rumors, and no one has (even) fessed up to" take responsibility for starting them, he said.

Brownlow refused to comment on future investigative plans.

Shults said investigators were being mostly tight-lipped for a good reason. "We have to be careful because we don't want any potential defendants" to be tipped off by a news media report naming them as suspects, he said.

Brownlow asked citizens "to report any information no matter how small or unimportant they might think it is."

A search of a landfill in Hamblen County June 13 did not result in the discovery of Maxwell's body.

Several other searches, including some using concerned volunteers in the community, have apparently not turned up any clues.

Although some officials have previously referred to Jeffrey Lee Stock, 41, as a "person of interest" in Maxwell's disappearance, Brownlow would not confirm Stock as a suspect or "person of interest."

Stock is in federal custody after a federal grand jury indicted him for allegedly traveling in interstate commerce and failing to register as a sex offender.

Stock was arrested in Cocke County on April 27 at 3:40 a.m., the day after Maxwell disappeared, and charged with a violation of the sex offender registry, court records show. He was arrested by detective Woods.
