Gardaí believe a man arrested in Jordan is Ahmed Al Saqar, the boyfriend of murdered American woman Jamey Carney, who they consider the prime suspect in her killing.The Irish Times understands the Garda has requested assistance and information from a number of other police forces as part of the murder investigation.However, they have not made any request, to the Jordanians or any other police force, for the arrest of the person of interest in the case.Al Saqar, the prime suspect who is believed to be from Jordan, left Ireland for Turkey immediately after the killing and before the woman’s body was discovered in her Killarney, Co Kerry, home.He had landed in Istanbul on a flight from Dublin before the remains were found.A requiem mass is due to take place at noon on Wednesday in St Mary’s Cathedral, Killarney, followed by a private cremation.Sources said they strongly suspected the man detained in Jordan is the same person being sought by detectives in Kerry over the murder. But they were unable to comment on why he had been arrested.No arrest has been requested by Ireland of any country because the murder investigation is in its early stages.Gardaí have not gathered enough evidence, or developed the case sufficiently, to seek the arrest of anyone in Jordan or any other jurisdiction.[ Who was American-born Killarney murder victim Jamey Carney?Opens in new window ]Investigators would only be in a position to request a suspect’s arrest in another country if the investigation had reached the stage of charges being approved by the Director of Public Prosecutions (DPP) against that person.A website operated by Jordanians in Ireland reported on Sunday that the man, whom they did not name, had been detained by the Jordan Public Security Directive but the Jordan authorities did not respond to a media query from The Irish Times regarding the arrest.However, a group called Jordanians in Ireland Forum have posted a message on social media commending the Jordanian authorities for arresting the suspect.“The forum highly commends the swift response and efficiency of the Public Security Directorate in Jordan which led to the arrest of the suspect last night where he is currently detained pending further investigation,” it said. However, a Garda source confirmed they had received reports that a person with the same name as Jamey Carney’s boyfriend, Ahmed Al Saqar, had been detained in Jordan but they were still awaiting confirmation that it is the same man as they are seeking to speak to.“This arrest was not made on foot of any request from An Garda Síochána and it’s for the Jordanian authorities to confirm the arrest and if it is the same person and on what basis he is being detained in Jordan,” said the source.Gardaí in Kerry declined to comment on the report and referred any queries to the Garda press office but they have yet to issue any statement.Gardaí are satisfied that Al Saqar caught a Green Coach from Mission Road in Killarney at 4.30am on July 7th to Bachelors Walk in Dublin and from there got a taxi to Dublin Airport where he caught a Turkish Airlines flight to Istanbul at 10.40am.Gardaí believe that he had already landed, or was about to land, in Istanbul Airport when they received a report at 1pm on July 7th that Jamey Carney had been found dead at her home in Homeland on the Muckross Road in Killarney.Detectives are continuing with their investigation and it is understood both forensics and analysis of the suspect’s phone activity could prove critical in their efforts to prepare a file for the DPP.Garda technical experts are trying to establish a location for the suspect via his phone activity at the time they believe Jamey Carney was murdered. They are anxious to try to establish where he was when he booked the 10.40am flight with Turkish Airlines from Dublin to Istanbul.Under Irish extradition law, gardaí can only seek the extradition of a suspect to either serve an existing sentence or for the purpose of charge for a new offence. They cannot seek the extradition of a person as part of their investigation or simply in order to question them.Ireland does not have a comprehensive bilateral extradition treaty with Jordan. Extraditions between the two countries are governed by the Extradition Act 1965 and are only granted where offences carry more than a one-year prison sentence.Earlier, Tánaiste Simon Harris said a “very active and ongoing” murder investigation remained under way and that “everybody wants to see justice done”.“Obviously, the Irish authorities will be working hand in glove with any and all international authorities that may be required to ensure justice for Jamey and the apprehension of her killer,” he said on Monday. “We obviously don’t comment on ongoing investigations beyond that, other than to say Ireland will be engaging intensively to ensure that justice is done in this case.”
