TMZ reports: Aaron Hernandez killed himself in his Massachusetts prison cell late Tuesday night using a bed sheet, this according to prison officials. The 27-yr.-old ex-NFL star had just been acquitted in a double murder case on Friday (which you can see below) and his lawyer Jose Baez had told TMZ Sports he believed Hernandez had a real shot at getting a previous murder conviction overturned.

But Wednesday morning officials at the maximum security Souza Baranowski Correctional Center in Massachusetts found Aaron dead in his cell. "Mr. Hernandez hangs himself utilizing a bed sheet that he attached to his cell window," a rep for the Massachusetts Department of Corrections said in a statement. "Mr. Hernandez also attempted to block his door from the inside by jamming the door with various items."Officials say Hernandez was discovered at 3:05 AM on Wednesday morning, and they tried to save his life. He was transported to a nearby hospital where he was pronounced dead at 4:07 AM.A prison official told local news there does not appear to be a suicide note at the scene.

 Aaron is survived by his 4-year-old daughter.
