First, you apparently missed this paragraph:
Rather, Lee and Momeni were portrayed by police as being familiar with one another. In the wee hours of April 4, they were purportedly driving together through downtown San Francisco in a car registered to the suspect.
Doesn't sound to me like the reporter is just speculating based on the LinkedIn profile.
Secondly, I'm pretty sure you have the wrong filing. The LinkedIn profile says "Inc", not "LLC", so I think it's probably file #4776106, which is still active, and registered with an address in Emeryville, which is where police were headed to arrest Momeni.
