Man 'acted out of instinct' when he fatally stabbed man who 'trespassed' on his Dublin home
Derek Boyd is on trial for the fatal stabbing of Mark Carroll, a man who had trespassed into his Dublin home. While the defense argues Boyd acted out of instinct to protect himself, the prosecution contends the attack was a deliberate act of violence.
Why it matters
The case highlights legal debates surrounding self-defense and the 'castle doctrine' in Irish law.
Murder accused Derek Boyd "acted out of instinct" when he fatally stabbed a man who "trespassed" on his north Dublin home and was entitled to protect himself if he was under attack, his lawyers have told a Central Criminal Court jury.
However, the prosecution said the accused man had chosen to pick up a knife in "a determined, murderous attack" and the deceased's return to the house "wasn't remotely threatening but entirely reasonable" as he was going back to "sort out" an earlier row.
Boyd took the stand at his trial on Thursday, telling a jury how he picked up a knife and "begged" the man he'd been drinking with just moments earlier to leave his home, only for the deceased to repeatedly threaten to kill him.
The accused man said that Mark Carroll grabbed him and, during a struggle, tried to take the knife.
