While sources confirm the trial and the coordination of the attack, the specific detail about the 'smuggled cellphone' from Wellington Prison is not explicitly detailed across multiple independent sources in the provided evidence, although one source mentions the relationship between the accused started at Wellington Prison.

The specific list of names for the co-accused is not corroborated by multiple independent sources in the provided evidence (the evidence for this claim index contains irrelevant information about carbon monoxide). However, some names appear in other claim evidence, but the full list as a set is not corroborated across multiple sources here.
