Feds arrested Oscar Hernandez Jr., 23, on Wednesday evening in Florida as part of a gun trafficking investigation related to the murder case against former New England Patriots tight end Aaron Hernandez.

According to the Associated Press, Oscar Hernandez Jr., no relation to Aaron Hernandez, is charged with obstruction of justice, witness tampering and lying to a federal grand jury investigating the transportation of guns from Florida to Massachusetts.

ESPN legal analyst Lester Munson broke down the significance of the man’s arrest and what it will mean to the Aaron Hernandez case on Thursday.

“The significance of these charges is that we now have the FBI making progress in the massive effort by the authorities to find the gun that was used in the murder of Odin Lloyd,” Munson said. “Oscar Hernandez was involved in obtaining guns for Aaron Hernandez, according to the government, and then shipping the guns from Florida up to Massachusetts, where Aaron Hernandez lived and where, according to the charges against him, he killed Odin Lloyd with one of these guns. If Oscar Hernandez Jr. decides to testify against Aaron, then the evidence against Aaron increases significantly."

Aaron Hernandez and two other men are charged in the June 17, 2013, murder of Lloyd, whose body was discovered about one mile from Hernandez's North Attleborough, Massachusetts, home.

Hernandez has been in prison and denied of bail since late June of last year.
