The gates were locked, a boy dying in a womans arms inside. This is what police have learned about the mass shooting in Orange, California

When police were finally able to enter the courtyard of the business complex in Orange, California -- where four people were fatally shot Wednesday -- they found a woman holding a wounded 9-year-old boy.

"It appears that a little boy died in his mother's arms as she was trying to save him during this horrific massacre," Orange County District Attorney Todd Spitzer said at a news conference Thursday, though he later added the exact nature of their relationship was still under investigation.The killings marked at least the 20th mass shooting since the attacks at Atlanta-area spas two weeks ago. Although investigations are still underway, police have begun to uncover what happened behind the locked gates of the courtyard, where the doors into the suites are, as well as what led up to the horrific violence.
"The preliminary motive is believed to be related to a business and personal relationship which existed between the suspect and all of the victims," Orange Police Department spokesperson Lt. Jennifer Amat said in a news conference Thursday.
"This was not a random act of violence," she said.
Five calls to 911 came in around 5:34 p.m., Amat said, and officers were at the complex about 30 miles south of Los Angeles about two minutes later.When they arrived, they heard shots being fired inside, but they were not able to enter immediately. From the inside, gates to the building's courtyard were locked "using a bicycle-type cable lock," Amat said.
It is unclear if they were meant to keep the victims inside or officers out, police officials said.After engaging with the suspect and firing shots, police used bolt cutters to enter the courtyard and found the suspect, who was injured, and took him into custody. Police had earlier said it was unclear whether his injury was self-inflicted.
In the courtyard, police also found the boy and the adult woman who survived. She was taken to a local hospital, where she is in critical but stable condition, Amat said.
Besides the boy, those killed were two women and a man, Amat said.
One of the women was found upstairs on an outdoor landing. The man was found inside one office building, and the other woman was found in a separate office building, according to Amat.
The suites where some victims were found belonged to a business identified as Unified Homes, Amat said, a real estate business specializing in mobile homes.

Investigators recovered a semi-automatic handgun and a backpack containing pepper spray, handcuffs and ammunition, which authorities believe belonged to the suspect.Police identified the suspect as Aminadab Gaxiola Gonzalez, 44, of Fullerton, California. He is at a local hospital in critical but stable condition, Amat said.Authorities said he would be arraigned Friday afternoon and would face four counts of murder, one count of attempted murder, and two counts of attempted murder of a police officer.
Gonzalez will also face felony enhancements for firearms and a premeditation charge, according to a news release from the Orange County District Attorney's Office.
"Prosecutors are also alleging the special circumstance of multiple murders," according to the district attorney's office.
CNN is working to determine whether Gonzalez is represented by an attorney who would comment on his behalf.
Gonzalez, who is believed to have been living in a motel room in Anaheim, arrived at the complex in a rental car and parked it in a lot nearby, Amat said.
A preliminary investigation by law enforcement officials concluded the suspect used a legally purchased firearm, she added.Authorities remained on scene Thursday to complete the investigation.
Spitzer said investigators were there for two reasons: to investigate the mass shooting, as well as the officer-involved shooting aspect of the case, to ensure both objectivity and transparency.
Spitzer emphasized that the suspect is eligible for the death penalty under California law because there were multiple victims.
Prosecutors are also looking into whether the fact that the gates were locked constitutes "lying in wait," Spitzer said, a special circumstance that would also make the suspect eligible for the death penalty.
During his tenure, Spitzer said he had reviewed nearly 20 murder cases for whether to pursue the death penalty, but he has never filed one death case.
"Asking a jury to pass down a verdict of death is the most serious consequence we ask, and it's the only consequence where a jury makes the decision as opposed to a judge," he said.
California has a moratorium in effect for its death penalty, under an executive order signed by Gov. Gavin Newsom in March 2019.
CNN's Alexandra Meeks, Sarah Moon, Joe Sutton and Holly Yan contributed to this report.It remains to be seen how Friday's attack might impact longer-term plans regarding security at the Capitol, a topic that has come under increasing scrutiny in recent weeks as many lawmakers and staff hoped to reclaim some sense of normalcy despite ongoing congressional investigations into the failures around the January 6 attack.
Barbed wire fencing that surrounded the Capitol complex for months after pro-Trump rioters stormed the building has since come down and thousands of the National Guard troops who were deployed in response to the insurrection have since returned home, though thousands still remain in Washington and were seen responding to Friday's attack.
The National Guard later confirmed Friday it had been deployed to the Capitol.
"The DC National Guard deployed a Immediate Response Force (IRF) composed of National Guard soldiers and airmen to the Capitol complex this afternoon to support the U.S. Capitol Police. Due to operational security, we cannot discuss further details regarding the IRF," the National Guard said in a tweet.
