PHILADELPHIA (KYW Newsradio) — Among the questions on most people's minds following mass shootings like the one in Thousand Oaks, California, on Wednesday night are "Why did this happen?" and "Why did the shooter pick this target?"

These are questions that could take a while for investigators to answer, especially because the suspect is among the dead, says retired FBI Supervisory Special Agent J.J. Klaver.

"Sometimes it's hard to apply a logical answer to a completely insane event," Klaver said.

If the suspect didn't leave any kind of note or explanation for his actions, the first thing investigators will do is interview people who knew or had recent contact with him, Klaver said.

Klaver says local law enforcement will lead the investigation with support from both the FBI and ATF. With all three working together, they'll try to find every piece of information available about the shooter.

"They're also going to do a full dive into his background: Pull all of his financial records, all of his online identities and records, look at any social media postings," he added.

This can be a lengthy process, Klaver said.
