A crack team from the US investigating the mystery disappearance of American woman Annie McCarrick has received a "promising" new lead that could help solve the case.
Michael Griffith, a New York-based lawyer who was hired by Ms McCarrick's family in the 1990s to help with the missing persons investigation, was contacted following an article that appeared in Monday's Herald.
The article revealed that Mr Griffith and ex-FBI agent Kenneth Strange were planning to travel to Ireland later this year to try and find out what happened to the 26-year-old.
"I received an email from a person who had read the article," said Mr Griffith.
"It was a lengthy and detailed email and it has presented us with a new lead that is very promising.
"I can't go into the details at this stage but a member of our team in Ireland is following up and will meet the person who wrote it to establish the credibility of the lead.
"The information that was disclosed is new to us and is of a very sensitive nature."
Ms McCarrick was last seen taking a bus to Enniskerry on the afternoon of Friday, March 26, 1993.
The last confirmed sighting of the tall, striking 26-year-old was made by a former work colleague on the No 44 bus to Enniskerry at around 3.30pm.
Her father John, who spent years trying to find out what happened to her, died in 2009 with no answers.
Mr Griffith and Mr Strange have joined forces with Annie's uncle John Covell to try and finally solve the mystery.
The men have identified a prime suspect in the case and are hoping to get access to the cold case file on the initial investigation.
The US-based team is being assisted by Brian McCarthy, an Irish private investigator who was initially hired by the McCarricks when their daughter went missing almost 30 years ago.
"We are also getting help from Joe Barnes, a criminal lawyer based in Dublin," said Mr Griffith.
"I will travel to Ireland in August and we are hoping we can get access to the garda files on this case. This is a cold case and we don't see why not."
At the time, gardai investigating her disappearance collected information to say that Annie visited Johnnie Fox's Pub, in the village of Glencullen, high in the Dublin Mountains.
Mr Griffith and the US-based team do not believe that information to be true.
"She didn't go there. Our own investigations have established that the sighting of her in the pub was a case of mistaken identity," he said.
"This new information would tally with our belief that she didn't go to the pub."
In an interview with the Herald, Ms McCarrick's aunt Maureen appealed to anyone who has information to share it with the private investigation team or gardai.
"Annie will never be forgotten by us," she said.
"I would ask anyone with information to put themselves in my family's position and try and imagine what the last 27 years without her and not knowing what has happened to her has been like.
"I would ask that they try and find it within themselves to come forward and disclose whatever they know."
