San Diego synagogue shooting

Authorities increased security Sunday at houses of worship one day after a teen gunman killed one woman and injured a rabbi, a child and another man during Passover celebrations at a San Diego-area synagogue.

. . . .

Accused gunman John T. Earnest, 19, of San Diego, is a nursing student at Cal State University San Marcos who lived about seven miles from the synagogue. 

[San Diego County Sheriff William] Gore said Earnest posted an online “manifesto” in which he criticized Jews and also celebrated the slaying of 50 Muslims at shootings at two mosques in Christchurch, New Zealand, last month.

The attack came exactly six months after 11 people were killed at a Pittsburgh synagogue. 

The manifesto echos common white supremacist themes.

. . . .

The suspect is accused of opening fire with an AR-style rifle at the synagogue shortly after services began Saturday morning. 

[Reportedly, the AR jammed.]

Passover celebrations are among the most important in the Jewish faith.

. . . .

An off-duty Border Patrol agent who was attending services at the synagogue fired at the suspect during the attack, hitting his car. 

The suspect then fled and was arrested without incident about two miles away.

. . . .

Earnest is also being investigated in connection with the arson at a mosque in nearby Escondido last month, officials said. 

In that incident, a fire broke out at 3:15 a.m. on March 24 at Dar-ul-Arqam mosque, also known as the Islamic Center of Escondido.

Update:

Earnest claimed in a manifesto also to have attempted to set fire to the Islamic Center of Escondido (Dar-ul-Arqam Mosque) last month. 

Someone did pour gasoline and start a fire, but congregants were on site and put it out. 

He also left graffiti referring to the New Zealand massacre of Muslims in Christchurch.
