Southern California Edison offices on the Rivergrade campus in Irwindale remained closed Monday. It is the first work day since last Friday when authorities say Edison employee Andre Turner, 48, shot and killed two supervisors and wounded two other co-workers before taking his own life.
"Law enforcement has been very involved in speaking to some of the employees who went through this experience last Friday," Steve Conroy, a spokesperson for SoCal Edison said.
At Edison headquarters in Rosemead, flags flew at half staff by order of Gov. Jerry Brown, marking the tragedy fresh in the minds of those who were there. Both the California and United States flags at Edison were lowered following a proclamation.
Authorities continued conducting their investigation on site and released 911 calls of the incident.
The Los Angeles Sheriff's Homicide department along with Irwindale police are trying to figure out why Turner took an otherwise usual work day and turned it into what Edison calls the most horrific day in its history.
Authorities say Turner gave no indication of what he was going to do when he arrived at work Friday morning. Officials would not say if there were problems with Turner at work but insist they are not considering company-wide layoffs.
"They are looking into the relationships and what took place," Conroy added.
All the victims worked in the Information Technology Business unit on the complex which houses over 1,100 Edison employees. Edison managers Henry Serrano, 56, and Robert Scott Lindsay, 53, were killed. Both had been with the company more than two decades.
Another victim, Angela Alvarez, 46, remains in critical but stable condition. Abhay Pimpale, 38, a contractor was released on Sunday.
Edison is conducting its own investigation.
"Security at our own facilities is very comprehensive. We are certainly taking a look at some other things that we may do in the near term. We've actually taken some additional steps as of Friday. Many of you may have heard our facilities were locked down after the event, all of our facilities. We will be taking some additional steps," Conroy explained, adding he could not provide details so as to not compromise the security measures.
Edison says it has work to do at the building before employees can get back to business and has no time table as to when the Rivergrade complex will reopen.
The company has created a $100,000 fund for the victims and their families. Grievance and crisis counselors are also being provided for the families and all employees.
