Landrigan was initially sentenced to death in that case, but his conviction was later overturned and he pleaded guilty to second degree murder.
[4] The jury found him guilty of murder and Landrigan himself prevented his defense attorney from presenting any mitigating evidence.
The sodium thiopental used in Landrigan's execution may have come from the UK, prompting objections from British diplomats in December 2010.

[10] The restrictions were based on "the European Union Torture Regulation (including licensing of drugs used in execution by lethal injection)".
