San Bruno police said Wednesday that Nasim Najafi Aghdam, the suspect in the YouTube shooting, went to a gun range Tuesday morning, shortly before going to the company's headquarters and opening fire. Police also confirmed they believe Aghdam was motivated by her anger toward company for limiting access to her videos.

The bottom line: Police say Aghdam, who died at the scene from an apparent self-inflicted gunshot wound, had no specific connection to any of the three people who were wounded in Tuesday's shooting.

At a press briefing on Wednesday, police also said:

  • Aghdam apparently entered YouTube through a parking lot.
  • Police have secured her vehicle, and agencies are serving two search warrants at homes in Southern California.
  • The gun was legally possessed and owned.

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
