Does anyone know this Matthew Pumar? Did he grow up here and go to school here? What school did he attend? Where was he working when he killed the poor victim? Why was he speeding down a residential street at 9:30am on a work day?

Usually in manslaughter trials like this, there is plenty of background information about both the victim and the alleged killer. In this case, apparently absolutely nothing about the killer was ever printed by the media.

I brought my family to mountain view to escape the madness of the big city. This guy pumar was obviously speeding. It takes a very large amount of force to rip someone apart. My daughter works at Castro elementary school and she waits at that bus stop every school day. There are always people and kids in that area. That guy pumar should get the maximum sentance for his stupidity but the system will probably slap him on the wrist and call it done. If he was a poor minority he'd get life. And that is societies fault.

Actually car accidents are more frequent in less urbanized areas due to higher speeds. Some even claim the crime injury/death risk in an average city, outside straight up ghetto, is lower than car injury/death risk in its burbs. This area of MV seems to combine the worst traits of urban and suburban, cars included...

I live in that neighborhood and before the designated left turn stoplight was installed there were regular accidents at this intersection. My car got hit by a woman making a left turn on the same corner. Despite the 25 mph speed limit on Escuela and the crosswalks, I see people racing through this area in their cars on a daily basis.

They were in the process of installing the left turn signals when the accident occurred last year.
