The trail has gone cold, the clues have dried up and an 77-year-old woman and her 10-year-old grandson from Deltona seem no closer to being found since they vanished more than 11 weeks ago.

The family of Lillian Martin, 77, and Joshua Bryant are captive in an anguished limbo. They can't move forward until they hear some news.

"I still need answers," a tearful Joanne Miller said, "I want people to know that this is still going on in my life.

"People still say, 'You haven't heard anything? You haven't found out anything?''' Miller continued, her voice cracking. "I know as much as everyone else, and that's basically nothing."

Martin and Bryant were reported missing the morning of May 12 by Miller. She told investigators the grandmother and boy were at home about 7 a.m. when her husband left work and she went to a charity event.

When Miller returned home around 11 a.m, she discovered her grandmother and brother missing, but Martin's car still in the driveway.

Since then, there has been few leads. That's despite thorough media coverage, including a segment on "America's Most Wanted."

"Did 'America's Most Wanted' result in leads? No,'' stated Cheney Mason, the family's attorney. "Not substantial, not insubstantial, nothing.''

The lack of progress in the case also has authorities stumped.

"It's certainly puzzling to all of our investigators and very frustrating that we haven't been able to unravel this mystery,'' said Gary Davidson, spokesman for the Volusia County Sheriff's Office.

Davidson said that the investigation continues, but little progress is being made.

"We still are following up on tips, leads and information. Some of them have been suspected sightings but, of course, none of them have panned out,'' Davidson said.

"I would not say that we're at a dead end, but at the same time, I can't say we're any closer to finding Lillian and Joshua."

One of the worst parts of Miller's wait, Mason said, is hearing news reports that a dead body has been found in central Florida. Human remains were found Sunday on the shore of a lake near Oviedo, about 15 miles south of Deltona.

"I watch all the news channels because I think you all are going to find out before I am,'' Miller said at a press conference Monday afternoon.

The family also announced that the reward fund has grown to $10,000.

The Federal Bureau of Investigation has joined the search. In the days following the vanishing, an agency behavioral scientist began to look into whether Martin's and Bryant's disappearance was the result of a planned crime.

FBI officials refused to comment Monday, referring all questions to the Volusia County Sheriff's Office.
