Former NFL star Aaron Hernandez, currently serving a life sentence in prison without parole for the first-degree murder of his former friend, semi-pro football player Odin Lloyd, is hoping to catch a break in the double-homicide case he still faces.

Hernandez, convicted of the 2013 murder of Lloyd, is facing double-murder charges in the drive-by shooting of two men, Safiro Furtado and Daniel de Abreu, in Boston in 2012. His legal team is trying to have key evidence thrown out based on an invalid search warrant, according to the Boston Globe.

According to Hernandez's lawyers, a search warrant that wound up with authorities seizing a Toyota 4Runner was acquired based on information from an associate of Hernandez's, Carlos Ortiz, who failed a polygraph lie detector test. The failed polygraph casts Ortiz's reliability in doubt, the laywers said, and invalidate the search warrant they acquired.

Ortiz told authorities about a home belonging to Hernandez in Connecticut where they found a silver SUV Hernandez was using the night of the double homicide.

The polygraph test determined Ortiz was "deceptive" when answering certain questions about the Lloyd case, but the prosecutor for the twin killings, Teresa Anderson, said that those results "did nothing to contradict" statements regarding the home in Connecticut. Anderson also said of the deceptive responses, "It doesn't automatically mean that everything that came out of his mouth was a lie."

Hernandez's lawyers have also sought to have witness intimidation charges dropped. Hernandez is accused of shooting a man named Alexander Bradley in the face and leaving him for dead out of paranoia that Bradley would talk about the double murder. Bradley, who has lost the use of one eye following the shooting, brought up the drive-by when the two had gone out to a club.

Hernandez believed there were undercover officers following him, to which Bradley allegedly responded "It's probably because of the stupid stuff you did up there in Boston."

Hernandez's lawyers scoffed at these allegations. "This is basically a concocted fantasy. This is not probable cause."
