INCIDENT CRIMINAL REPORT Alameda County Sheriff?s Of?ce Agency: ETS ORI: CA00100000 Case Number: 15-019904 Supplement Information Supplement Date Supplement Type Supplement Of?cer 11/25/2015 09:11:20 GENERAL SUPPLEMENTAL (201428) SKIDGEL, MATTHEW A Contact Name I Supervising Of?cer (109671) DESOUSA, ANTHONY 3636 Supplement Narrative On Wednesday, November 19, 2015, I worked for the Alameda Office (ACSO) as a Detective assigned to the Special Victims Unit (SVU). I learned that a suspect, Stanislav Petrov, led ACSO patrol Deputies on a pursuit into the city of San Francisco on Thursday, November 12, 2015. The pursuit ended when Petrov crashed the stolen vehicle he was driving into a vehicle parked near the intersection of Stevenson Street and 14th Street, in San Francisco. Petrov led Deputies on a foot pursuit and was eventually caught and arrested. Petrov resisted the efforts put forth by the patrol Deputies to affect his arrest and force was used to overcome his resistance. Petrov sustained several injuries and was transported to the San Francisco General Hospital, located at 1001 Potrero Avenue, in San Francisco. It was unknown which injuries Petrov. sustained from his crash and which injuries he sustained from the force used to overcome his resistance. My supervisor, Detective Sergeant A. DeSousa, instructed me to write a search warrant so the ACSO could obtain Petrov?s medical records from the San Francisco General Hospital. I authored the search warrant and took it to the Hayward Hall of Justice, where the Honorable Judge K. Murphy reviewed and signed the warrant. I contacted the San Francisco General Hospital and faxed them a copy of the warrant. I was informed that Petrov was currently in surgery and that additional diagnoses would likely be made at later dates, as additional procedures were done. San rancsico General Hospital Records Supervisor Karen O?Donnell said she had the search warrant in her possession and assured me she would provide me with all of Petrov?s medical records as soon as he was done receiving medical treatment and discharged from the hospital. In the meantime, the only medical records that were currently available were from Petrov?s admission to the San Francisco General Hospital Emergency Room. Those records were faxed to me and I subsequently packaged them and submitted them into evidence at ETS. I learned that Petrov had. a Samsung Galaxy 4 Note phone on his person when he was taken into custody and the phone had been submitted into evidence at the Eden Township Substation (ETS). I signed the phone out of evidence and noticed it had been packaged along with several other items that Petrov had possessed when he was arrested. My partner, Detective K. Lydon took possession of Petrov?s Samsung phone and subsequently authored a search warrant so the phone?s contents could be downloaded to a disc. Detective Lydon later repackaged and submitted the phone back into evidence. (Refer to Detective Lydon?s supplemental report.)

I found it odd that Khalsa?s driver license had been found in Petrov?s possession. accessed several law enforcement databases and eventually located contact information for Khalsa. I spoke with Khalsa, identi?ed myself and explained how I came to possess his driver license. Khalsa told me his license had recently been stolen from him on October 26, 2015, when he was in San Francisco. Khalsa told me the following, in Summary. On the aforementioned date, about 2300 hours, Khalsa sat in his vehicle near the intersection of Mission Street and 19th Street, in San Francisco. Khalsa fell asleep and awoke to the sounds of a man rummaging through his vehicle. Khalsa said the man was sitting on the front passenger seat and held Khalsa?s wallet and iPhone 6 in his hands. The man immediately exited Khalsa?s vehicle and ?ed on foot with Khalsa?s property. Khalsa said he did not get a very good look at the man who stole his property and did not think he could positively identify him. Icontacted the San Francisco Police Department (SF PD) and a copy of the report (#15093 7975) was faxed to me. I read the report and the information contained in it was essentially the same as what Khalsa told me. I packaged and submitted the SFPD report into evidence at ETS. On Tuesday, December 01, 2015, I came to work and noticed Petrov? 5 medical records had been sent to my of?ce, via Federal Express, from the San Francisco General Hospital, per the court order. I packaged and submitted the medical records and submitted them into evidence at ETS. This is a supplement to the original report. Case Status: Printed: 2/26/2016 10:11 Page 52 of 62
