Last week, ABC 7 News in San Francisco reported that 49ers DE Ray McDonald called a San Jose police officer who also worked security for the 49ers, that that officer arrived at the scene of McDonald's arrest on domestic-violence charges. Now the station adds more detail—the cop was on duty and in uniform, even as he showed up independently of SJPD.

Police sources said last week the San Jose police officer is Sgt. Sean Pritchard and also works security at 49ers games. Sources in the police department also said Pritchard was on duty the night he showed up at Ray McDonald's home. He had worked a security job earlier in the day at the sprawling Santana Row complex.

Sources say he went to his regular job at the police department, changed into his uniform and was doing paperwork at his desk. That's when sources say he got the call from McDonald. Pritchard then got into his police car and rushed over to the football player's home.

The officers who responded to the scene were reportedly surprised to see another police vehicle and Pritchard.

Update: The San Jose Mercury News reports that Pritchard had already been at McDonald's house that night. Why? Just hanging out at McDonald's birthday party.

Last week, San Jose police handed off the case to the prosecutors' office, which will determine whether to bring charges.
