A CONVICTED murderer has been sentenced to life in prison for the murder of another inmate at HMP Long Lartin.

Victor Castigador, 61, has been sentenced to a whole life term for the murder of Sidonio Eugenio Teixeira at Birmingham Crown Court today (Friday).

The prisoner, who was in jail for the murder of two people and the attempted murder of another two people in London in 1990, has been sentenced after pleading guilty to murder on Friday, September 23.

The defendant was found to have inflicted serious head injuries to the victim after landing multiple blows to his head with a rock during the attack at HMP Long Lartin on June 20.

Sidonio Eugenio Teixeira suffered the injuries at the hands of Castigador as both prisoners were making their way to the prison workshop.

He was pronounced dead on the way to hospital.

Detective inspector Paul Hardman led on the investigation.

He said: "The sentence indicates the severity of the attack which was brutal and unprovoked.

"The defendant showed no concern that his actions could ultimately result in taking another life and instead acted to settle a score in a calculated and vengeful way."
