The teenage son of a Belfast murder victim has told a jury how he watched his father's girlfriend stab the man in the body and head as he cried out for help.
Thomas Robin (17) said he saw an “angry and evil” look on the face of Angeline Mitchell as she plunged a kitchen knife into his father in the early hours of May 11 last year.
Mitchell, from Lindsay Court in Belfast, denies murdering her 44-year-old partner Anthony Robin in his Fitzroy Avenue flat.
Thomas Robin, who gave evidence via a video link at Belfast Crown Court, said his father and 39-year-old Mitchell had started arguing about another of his sons who had been arrested earlier.
He said his father joked with Mitchell that she was a tout who had done sexual favours for police and slept with older men.
The teenager said that he went into the hall after hearing his father calling out his name for help. He said he saw Mitchell stabbing him a number of times.
Thomas Robin said he grabbed the knife from Mitchell and hid it because he didn't want her to get her hands on it again.
He added that she went into the living room and sat on a sofa “as if she didn't care” and he claimed she said: “He deserved it, the b******.”
Mitchell told police she was acting in self defence after Robin knocked her to the ground and attacked her with a canoe paddle.
