A 20-year-old Limerick man has been jailed for life after being found guilty of murdering a young man who “was in the wrong place at the wrong time” in December 2009.

A senior Garda witness has told the murder trial of a Limerick man that he suspected the 20-year-old shot dead a carpenter in retaliation for an arson attack on his mother's van.

A 22-year-old witness in a murder trial told Gardaí he was in the passenger seat of a car when his friend, who was driving, reached across him with a gun and shot a man in front of him.
