John Earnest who killed one and injured three at the Poway synagogue in California pleaded not guilty of the charges brought against him.

Earnest, 19, is charged with one count of first-degree murder and three counts of attempted first-degree murder which can all be classified as hate crimes.

He was also charged with a single count of arson on a mosque in Escondido, CA that caught fire last month. The prosecution levied this charge based on the manifesto Earnest published 2 hours before the synagogue shooting.

If convicted of the charges, Earnest could face the death penalty or a life sentence without parole.

The prosecution said that Security cameras caught the entire shooting on camera, and the suspect was arrested shortly after the act, with five magazines containing 50 bullets, a tactical vest and a helmet on him. The weapon apparently got stuck allowing him to shoot ten bullets.

At the hearing, Earnest was behind a glass panel, wearing blue prison clothes from the prison system, and quietly gave one-word answers to procedural questions.

Judge Joseph Brannigan scheduled a subsequent hearing for May 30th and denied granting him bail, calling Earnest ”an extreme threat to public safety”. He is scheduled to have his preliminary hearing trial on July 8th.

Authorities also accused him of a fire caused by a fire last month in a mosque in Escondido, which in his alleged manifesto published before the attack claimed to have perpetrated it.

The Police investigating the shooting attack estimate that Earnest acted alone and was not part of any organized group.
