Car Shootings on 101

Have you guys seen this article? Three shootings from cars to other cars on 101 since Sunday. One man died near Burlingame, one wounded in SF, and one wounded in San Jose.

From the SF Chronicle article:

No suspects have been named in any of the three shootings, and witness descriptions of the possible shooters vary.
Burlingame police described the occupants of the three cars near Wilson's Honda at the time of the crash as African American, Tongan or Samoan men in their 20s. The BMW driver described the man who shot him as an African American man in his 30s, the CHP said. San Jose police have not released a description of the shooter in their case.

I wonder if they are related shootings.
