The jury came to its decision Monday morning at the end of Harry Burkhart's second sanity trial. The jury's decision means Burkhart faces prison time as opposed to time in a state mental hospital.

In 2016, a judge declared a mistrial in the sanity phase of the trial after jurors became deadlocked on Burkhart's state of mind.
During the trial, public defender Steve Schoenfield said Burkhart's mental history shows that his client is severely mentally ill and developmentally disabled, emphasizing that Burkhart was in a psychiatric hospital just four months before the arsons.
However, prosecutors countered that Burkhart knew exactly what he was doing and that he was angry at the United States after his mother was deported.
"Revenge is what the defendant wanted, and it's what he got," said prosecutor Joy Roberts.
The prosecution went on to say that the way Burkhart set nearly 50 fires in and around Hollywood six years ago shows calculation and premeditation.
They believe he methodically bought fire-starting materials and chose his targets, that he was aware he was doing something wrong because of the care he took to avoid getting caught.
Burkhart is scheduled to be sentenced March 23.
