Two senior law enforcement officers who were described in the incident said the car that killed one person outside a California fertility clinic and injured four others was driven by anti-Natalist ideology.
The suspect, identified by authorities as Guy Edward Bartos, is believed to have exploded an explosive in Saturday's attack, which claimed his own life.
Investigators focus on social media posts made by the suspect. This includes 30 minutes of audio recording. The posts and recordings are still validated, but authorities believe they reflect the ideology behind the bombing. Anti-natalism refers to the belief that no one should have children.
The same person could also be linked to an online forum post from earlier this month in which an individual committed suicide using an explosive device, sources said. It is also investigating YouTube accounts that feature videos of experiments using homemade explosives under the same moniker.
At a press conference on Sunday, authorities said they believe the suspects are trying to livestream the attack and are looking into what they call “manifesto.”
The suspect was dealing with depression and reportedly had personal relationship issues, law enforcement officials close to the investigation said. Authorities said he was 25 years old and was from Twentynine Palms, who is running a search warrant.
On Saturday, multiple law enforcement tactical officers were seen outside their Twentin Palms residence, about an hour away from a targeted fertility clinic.
The FBI and Palm Springs Police Department have originally refrained from identifying suspects.
The severity of the blast injuries caused by those injured by those injured, but all were released from hospitals, officials said.
The explosion that the FBI deems a terrorist act took place around 1199 North Indian Canyon Dr., around 11am, according to city officials. The streets have many medical facilities, including the Desert Regional Medical Center.
The obvious target of the attack, an infertility clinic called the American Reproductive Centers (ARC), confirmed in a Facebook post that the vehicle exploded in a parking lot near the Palm Springs facility.
The explosion caused damage to multiple buildings and businesses within a 250-yard blast radius, officials said. Witnesses said they could feel the explosion being heard from miles away.
Law enforcement officials told NBC News.
On Sunday, officials continue forensic inspection of physical evidence in and around the explosion zone, and canvas the area of video footage to establish a timeline for the event leading up to the explosion.
Authorities are seeking interviews with family, friends and peers, and are reviewing online posts that may be linked to social media accounts and cases. At a press conference on Sunday, authorities called for the public's help in identifying Berthos' moves and confirmed they were driving the 2010 Silverford Fusion.
The incident was probably one of the biggest bombing investigations, Davis said.
Palm Springs Police Chief Andy Mills believes the explosion is an isolated incident.
“I'm sure this city is safe,” Mills said Sunday. “There is no continuous threat.”
