The Dolphins, as is typical on legal matter, refused to comment as an organization and also said Pouncey had no comment, according to SI.com.

According to SI.com, neither the Patriots nor Dolphins knew that Pouncey was about to be served with a subpoena. But, immediately after the game a total of seven police officers were just outside the locker room and speaking with NFL Security officials, according to the SI.com report.

Si.com said that a source told the website that shortly after the first murder investigation began, looking at the Lloyd murder, “signs that Hernandez was involved with a large-scale, multi-state gun running operation began to emerge.”

Pouncey has not been implicated in any crimes in the case and is being viewed by authorities as a material witness who could help the case.
