Mr. Clark 5 had called dispatch to report that “someone had attempted to burn down his garage (which is 6 attached to the residence) and the garage door was still smoldering.” Dkt. 13-11 at 5. Mr. Clark 7 advised dispatch that he “did not need fire to respond.” Id. 8 Deputy Denton arrived at the scene, and he requested a fire investigator. Dkt. 13-10 at 12. 9 Chief Smith responded along with Officer Joey Howard, who was assigned to Chief Smith for 10 field training. Id. Upon arrival, Deputy Denton briefed Chief Smith of the circumstances and 11 showed Chief Smith burns on the garage door, which Chief Smith proceeded to evaluate. Id. at 12 12. According to Chief Smith, the fire had self-extinguished, but charring and damage was done 13 to the garage door. Id. Chief Smith determined that “[t]he fire [wa]s believed to have occurred 14 sometime during that night while [Ms. Clark], her mother and [f]ather were sleeping inside the 15 residence.” Id. Chief Smith noticed and took a picture of a spike strip6 laid across the driveway, 16 concealed by dirt that did not match any of the dirt around the home and appeared to have been 17 brought in from another location. Id. at 4, 13; RT 103-104. Chief Smith explained that he was 18 “not sure what [the spike strip] was for, either to take out fire trucks responding to the residence or 19

20 3 McCormack spells his ex-fiancée’s last name as “Clarke.” See Dkt. 1 at 3. However, police and fire reports spell her last name as “Clark.” See Dkts. 13-10, 13-11. The Court uses the latter 21 spelling.

See 25 Dkt. 13-2 (Resp’t Ex. C - RT). 26 6 Deputy Denton testified at the preliminary hearing that the evidence he collected included two spike strips, which he described as “a piece of rubber hose with nails stuck through it at various 27 angles and sharpened.” RT 70-71, 87-88. In general, a spike strip is “a long thin device with 1 people leaving the residence to get away from the fire.” RT 21. 2 Ukiah Fire Department Fire Investigator, Chief Justin Buckingham, arrived at the scene 3 next.

Dkt. 13-10 at 14; Dkt. 13-11 at 9; RT 113. Deputy James 17 introduced them to McCormack’s father, Steve McCormack, who escorted them to the 18 McCormack residence. Dkt. 13-10 at 14. 19 Upon arrival at the McCormack residence, Chief Smith turned on his audio recorder which 20 recorded thirty-three minutes of the encounter, first with McCormack’s father and then with 21 McCormack, prior to the battery dying. Id.; Dkt. 14 (Resp’t Ex. L - DVD Recording). Chief 22 Smith located McCormack sleeping in his bedroom, Dkt. 13-10 at 14, which was a separate 23 structure from the McCormack residence, RT 114.

Dkt. 14 4 at 6:09-6:14; RT 116. McCormack subsequently “unlocked his cell phone and granted [Chief 5 Smith] permission to search [McCormack’s] cell phone.” Dkt. 13-10 at 14; Dkt. 14 at 6:10-10:40. 6 Upon searching McCormack’s phone, Chief Smith found “a total of five open web browser titled 7 the following: #1 Tinder, #2 Reverse Phone Lookup, #3 homemade spike strips - Google search, 8 #4 [P]otter [V]alley structure fire - Google search, [and] #5 About ANORO ELLIPTA for COPD 9 symptoms.” Dkt. 13-10 at 14-15; see also RT 116, 118-119, 124-126.
