FIRST APPELLATE DISTRICT

DIVISION TWO

THE PEOPLE, Plaintiff and Respondent, A171424

v. (Sonoma County DAVID STEVEN AVERILL, Super. Ct. No. SCR-762854-1) Defendant and Appellant.

THE PEOPLE, Plaintiff and Respondent, A171643

v. (Sonoma County THOMAS WILLIAM GRIEGO, Super. Ct. No. SCR-762854-2) Defendant and Appellant.

After a joint jury trial, defendants David Steven Averill and Thomas William Griego were found guilty of aggravated kidnapping under Penal Code section 209, subdivision (a) (section 209(a)), conspiracy, two assaults with a firearm, burglary, and other offenses. In these consolidated appeals, Averill and Griego claim instructional error, insufficient notice of the prosecution’s theories of aggravated kidnapping, and insufficiency of the evidence for aggravated kidnapping, assault with a firearm, and conspiracy to commit those offenses.

1 Averill also argues he should have been tried separately from Griego, their joint trial violated his Sixth Amendment rights, his trial counsel provided ineffective assistance in various ways, the prosecutor engaged in misconduct, and his convictions for possession of a firearm and ammunition violate the Second Amendment. We affirm. FACTS AND PROCEDURAL BACKGROUND By a fifth amended eight-count information, the Sonoma County District Attorney charged Averill and Griego with “[s]eizing and [d]etaining for [e]xtortion” victim Denise (§ 209(a))1; count 1); conspiracy to commit aggravated kidnapping, assault with a firearm, and residential burglary (§ 182, subd. (a)(1); count 2); two counts of assault with a firearm (§ 245, subd. (a)(2); counts 3 [victim Denise] & 4 [victim Ken]); wearing a mask or disguise for an unlawful purpose, a misdemeanor (§ 185; count 5); and first degree burglary with a person present (§ 459; count 8). Averill was further charged with possession of a firearm by a felon (§ 29800, subd. (a)(1); count 6); and possession of ammunition by a felon (§ 30305, subd. (a)(1); count 7). Averill was alleged to have personally used a firearm in the commission of counts 1 and 8. (§ 12022.53, subd (b).) For Griego, it was alleged that a principal in count 1 was armed with a firearm. (§ 12022, subd. (a)(1).) The

1 On appeal, defendants refer to count 1, violation of section 209(a), as

“kidnap to commit extortion” and the Attorney General calls it “kidnapping for extortion.” We will refer to a violation of section 209(a) as “aggravated kidnapping under section 209(a)” or “aggravated kidnapping.” (See People v. Harper (2020) 44 Cal.App.5th 172, 190 (Harper) [section 209(a) describes four types of “ ‘aggravated kidnapping’ ”].) We refer to the victims, Denise and Ken, by their first names in consideration of their personal privacy interests. (Cal. Rules of Court, rule 8.90(b)(4), (10).) Undesignated statutory references are to the Penal Code.

2 district attorney also alleged numerous sentencing factors in aggravation relating to the crime and to defendants. At trial, Averill and Griego acknowledged that they went to the home of Denise and Ken on May 17, 2023, and tried to take property by force.2 They did not dispute the authenticity of text messages between Averill and Griego sent in the days before May 17, which showed them discussing a plan to obtain cash that would require at least one firearm. But they contested the charges of aggravated kidnapping under section 209(a) and assault with a firearm, along with the charge of conspiracy to commit those offenses. The Prosecution’s Case The prosecution’s theory for aggravated kidnapping under section 209(a) was that Averill targeted the victims because he knew there was a safe hidden in their home; Griego agreed to help with Averill’s plan to get money from the safe; and Averill and Griego threatened Denise with a gun, held her down and tried to tie her up, as argued in the prosecutor’s closing argument, “in order to coerce her or Ken to give them the combination to the safe.” At trial, the prosecution presented evidence of the following. Denise and Ken are married and have lived at their residence in Sonoma County since the 1990’s. They extensively renovated their property, rebuilding structures over the course of years while they lived on site. Averill was on the construction crew for several stages of the renovation project, including the final stage, which involved installing a safe in concrete under the floor of a walk-in closet in a bedroom in the main house. To access the safe, there is a hinged panel on the closet floor covered in carpet. (Ken

2 In closing argument, Averill’s counsel acknowledged that Averill

attempted a home invasion robbery and told the jury to vote guilty on count 8 (first degree burglary). Similarly, Griego’s counsel conceded there was a conspiracy to commit residential burglary and an attempted robbery.

3 described the safe as “well hidden.”) Only Denise, Ken, Ken’s son, and the construction workers know the safe existed, and only Denise and Ken know the combination to the safe. The property is enclosed by a six-foot fence with an automatic gate at the front. The gate can be opened from the street side by using a keypad or from inside the house using a switch. (So there is no way to open the gate from inside the front yard; one must go in the house.) Shortly before 8:30 on the morning of May 17, 2023, Denise was doing yard work in the front yard with a leaf blower while Ken was asleep inside the house. Denise decided to clear leaves on the street side of the gate, so she put the leaf blower down and went inside the house to open the gate. Denise testified that when she returned to the front yard and picked up the leaf blower, she saw a man “completely masked with a gun” pointed at her. She stumbled back and fell, and the man moved closer to her. She yelled, and he told her to calm down. She fell again, and the man got on top of her. Denise began screaming for help, and the man said, “ ‘Be quiet or I’ll shoot you.’ ” Denise screamed and struggled, while the man with the gun straddled her and tried to keep her pinned down. A second man appeared. As the first man (with the gun) tried to hold Denise’s wrists together, the second man tried to put zip-ties on her wrists. At some point, the man with the gun “jumped up and the other guy got on top of [Denise] and he started saying to [her] ‘don’t turn this robbery into a murder.’ ” The second man “started shoving a cloth in [her] mouth,” and Denise bit him. She heard “the sound of tape ripping” and thought someone was going to put tape over her mouth. The men “started getting rougher with” Denise, and she felt gravel being pushed in her face. She kept screaming for help.

4 Ken testified he was awakened by “a female voice screaming and the leaf blower at the same time.” Ken got up quickly and went to the office, which has a large window facing the front yard. He slid open the window (a screen remained in the window frame) and saw Denise lying on the ground struggling with a man “clothed in black” who was on top of her. Ken yelled, and the man “got off of her and ran towards the window where [Ken] was.” The man “used the gun in his hand” to “rip[] the [window] screen open.” With “his arm pushed through” the window, the man pointed the gun at Ken and commanded him to lie face down or he would shoot. The man’s gun was a black semi-automatic pistol. Ken got down on one knee and looked around his office for something he could use as a weapon.
