An Irish engineer robbed and murdered while working in Mozambique was killed for the cash he was carrying to pay local workers, detectives believe.
Quantity surveyor William Deasy, from Dublin Pike, north of Cork city, was beaten to death four weeks ago after he left work at a mine on the north-east coast of the east African country.
The 32-year-old's body was discovered two days later near to where he lived, with his car found abandoned 124 miles (200km) away.
Investigators believe his killers knew he often carried big sums of cash to pay other workers at Kentz engineering, according to sources.
Police chiefs and government officials in Mozambique vowed to carry out a full and thorough investigation into the vicious attack during a meeting with Irish junior minister Joe Costello.
"There is a family deeply bereaved, they had lost a loved one, a son, who was an extremely bright, capable young man and they lost a son at this distance," said Mr Costello, who is in Mozambique.
"If any closure was to take place, there has to be a full and thorough investigation. Being here at this point and time it was appropriate to raise it at the highest level and I will be speaking to the family when I return."
Mr Deasy joined Kentz after he qualified from Cork Institute of Technology in 2011. He was working on a project at Kenmare's Moma mine.
Mr Costello held talks with senior police and the country's Minister for Foreign Affairs Oldemiro Baloi at the request of the Deasy family.
The Irish minister was in the country to see the work of some Irish Aid funded projects.
