So let's play a game where we ignore every single thing the Meyers' family has stated.
What do we know for sure?
We know very very little.
We know TM is dead. She was shot in front of her house -- maybe in the yard, maybe in the car, maybe on the street. The police report says the autopsy report said the cause of death was a gunshot wound to the head. (The police report did not specify what caliber of bullet hit her in the head.)
If we assume that physical evidence is described accurately in the police report, we know that police recovered 6 .45 caliber shell casings at the Alta Drive/Villa Monterey shooting scene, and that they recovered 9 fired .45 caliber casings and 3 fired 9mm casings at the Meyers cul de sac shooting scene, plus one unfired 9mm round found in the front passenger seat of the Meyers vehicle.
We know that Erich Nowsch has been arrested and charged with the murder of TM, attempted murder of BM, and unlawfully discharging a weapon.
We know that Erich Nowsch lived/lives about a block away from the Meyerses.
We have seen fuzzy surveillance video of a grey or silver car driving on a street. To my knowledge, we do not know where this camera was located or which direction it was pointing or what time the video was recorded.
We know there was a description and a police sketch of the suspect that did
not resemble EN, and we know that the police said no one needs to continue looking out for the suspect as described or as shown in the sketch.
So far as I know, those facts might be about all that we know with 100% certainty or near-100% certainty.
We can place some credibility into some things that some people have said:
The police report said that two friends of EN told police that EN told them about the car chase and that he "got those kids" and that he told them he fired his gun at the other car/people 22 times. We don't know of any reason in particular to disbelieve those two friends, so I tend to believe them. I believe that the recounting by those 2 friends of what EN told them about the car chase and shooting is largely accurate, although minor details may be incorrect, either because EN was incorrect, or the friends misremembered what he said, or the cops paraphrased inaccurately in their report. But I think that the overall description of the incident is
probably correct, including the description of the chase and shootings as one single extended incident that did not include any point at which TM left the scene, went home, dropped off her daughter, picked up her son and his gun, and went back out to find the silver car again.
Those two friends also told police that EN showed them the gun he said he used, and his ammunition and spare magazines. When shown three different calibers of ammunition (9mm, .40 and .45), both the friends identified the .45 as the type of ammo EN had. There's a big enough difference between those rounds that I tend to believe they identified the ammo accurately.
We know that the police report says that Brandon told police his mother came home and sent his sister inside and told him to get his gun and come with her to find the silver car. We don't know that what Brandon told police is true. We do know that early on, the Meyers family said that the silver car followed mom & sis home and that Brandon emerged from the house with his gun to return fire. So we know that the police report attributes statements to Brandon that are in contradiction to what Brandon's father originally said publicly. But we don't know which version is correct, or if in fact either of those versions are correct.
We know certain things that neighbors have said -- because we've seen them say it on video -- but we don't know the truthfulness or accuracy of any of those statements.
We know certain things that Meyers family members have said, but we don't know the truthfulness or accuracy of any of those statements.
