A brown skinned young man in white Tshirt removed the screen from our bathroom window, which was about 4 inches open at the time. I was working in my office and heard him, dropped what I was doing to go investigate, and scared him pretty badly. He was about to pull the window open further, but dropped the screen on the ground and bolted. I gave chase and ran after him barefoot as he leapt into a small, robin's egg blue, custom pick-up driven by another man with curly dark hair. They proceeded just fast enough to leave me gradually behind down Marin Ave, left onto Casino, left onto Yuba, and right on Shasta to turn right onto Amador, the service road to I-80, before I lost them. It was 12:46 when I got back into the apartment in time to answer a call from Lisa and beg-off temporarily in order to call 911. Despite our Richmond address they forwarded me to the San Pablo Police. Officers arrived just after 1:00. One went on to scout while the other took my statement, made a strenuous case for our being in San Pablo and not Richmond, dusted for prints in and out, found none and offered as much hope of other results, and then went on his way as Lisa was arriving home around 1:30 with Rosie, fertilizer, seedlings, and anti-snail measures.
