Even if you're not a comic book movie fan, you remember the horrific events in an Aurora, Colorado movie theater in 2012. Gunman James Holmes opened fire into the theater during a midnight showing of The Dark Knight Rises, killing 12 people and injuring another 70.
It was one of the worst mass shootings in America, a country that has had far too many of them in recent years.
The jury at Holmes' three-month long trial seemed to agree, because the gunman has been found guilty of 24 counts of murder with which he was charged. He was formally charged with 165 counts of murder and attempted murder, with the 24 guilty counts all coming from the dozen people he tragically murdered.
Holmes pled guilty by reason of insanity, so it was up to the jury to determine whether or not he was mentally sane and sound during the time of the shooting massacre.
In Colorado, the death penalty is legal and a single guilty verdict on a murder charge automatically makes one eligible for it. The trial will move to sentencing Holmes next, where it will be determined whether he receives a life sentence or the death penalty.
Holmes showed no emotion as he stood at the defense table with his attorneys as the verdict was read.
He previously told prosecuting attorneys that he had started planning the attack on the theater months before the massacre happened, buying a ticket to The Dark Knight Rises almost two weeks before the movie's release.
