THIRD APPELLATE DISTRICT

(San Joaquin) ----

THE PEOPLE, C097817

Plaintiff and Respondent, (Super. Ct. No. LOD-CR- FECOD-2017-0000573) v.

KENNETH VANDERFORD,

Defendant and Appellant.

Defendant Kenneth Vanderford appeals from his convictions of murdering Dorothy Wiederrich and Alan Gregor and for robbery, burglary, and arson. He contends the trial court committed instructional errors, the court improperly admitted unqualified expert witness testimony, trial counsel rendered ineffective assistance, the prosecutor committed misconduct when cross-examining defendant and when arguing in rebuttal, the court committed sentencing error, and cumulative error. Except to strike one of the two multiple-murder special circumstances found true, we affirm the judgment.

1 FACTS AND HISTORY OF THE PROCEEDINGS Defendant was tried with codefendant Kevin Etherton. Each had his own jury.

Prosecution’s Case in Chief

Murder of Dorothy Wiederrich

Dorothy Wiederrich lived alone in Lodi in 2016. At the time of her murder, she was 74 years old. Wiederrich’s son, Johnny B., visited Wiederrich each weekday from morning until the afternoon. Another son, William B., visited Wiederrich on Sundays. He would take her to church and then to lunch. Family and friends knew Wiederrich was “fairly well-off.” She lived in a nice neighborhood and drove a new car. She was a “pretty private person.” If an uninvited guest came to her house, she might speak through the door to the person, or she might ignore the knock completely. She would not open the door. Her family members would call her before going to her house and inform her they were coming. The house’s front door was secured by a dead-bolt lock operated by a digital keypad outside. Entering a code on the keypad would unlock the door. At the time of Wiederrich’s death, Johnny, William, William’s daughter Amber C., a housekeeper, and Katrina J. knew the code to open the door. Wiederrich had hired Katrina to perform errands at the house and keep her company. Katrina worked every weekday and arrived at a set time. She entered Wiederrich’s house by using the key code. At the time, Katrina was defendant’s wife. Wiederrich’s granddaughter, Amber, met Katrina in a halfway house in 2005, and they became close friends. Katrina and defendant lived with Amber rent free in 2013 or 2014 to save money “to get back on their feet.” Amber asked them to leave when she realized they had not saved any money.

2 Amber had introduced Katrina to Wiederrich. Katrina had a background in caring for elderly persons. When Wiederrich was looking to replace her caregiver, Amber recommended Katrina to Wiederrich. The two developed a good relationship. Katrina and defendant attended Wiederrich’s family events. Defendant and Wiederrich also appeared to get along. On occasions, Katrina took defendant with her to Wiederrich’s house. Defendant had been to Wiederrich’s house two or three times by himself, once according to Wiederrich to pick something up or drop something off for Katrina. Katrina denied ever sending defendant to Wiederrich’s house to pick something up or drop something off. She had never known defendant to go there without her. She denied sharing the house’s key code, and she denied giving the code to codefendant Etherton. At one point, Wiederrich helped Katrina and defendant buy a vehicle. They were having financial problems, and their car was unsafe. Wiederrich loaned Katrina money to purchase a red Ford F-150 pickup. Amber normally saw defendant driving the truck. Katrina worked for Wiederrich for between one and two years. Eventually, Wiederrich let Katrina go. Katrina had stopped showing up for work on a consistent basis. She had problems with her back and suffered from mental health issues. Katrina and defendant were upset when Wiederrich let Katrina go, defendant more so than Katrina. Defendant wanted to speak with Wiederrich about it, but Amber and her husband told him it was not necessary. Wiederrich’s son Johnny began providing care for Wiederrich after Katrina was let go. On February 12, 2016, Johnny left Wiederrich’s house around 3:30 p.m. Wiederrich was fine when he left. He did not expect Wiederrich would have company that night. Amber called Wiederrich that evening at 5:17 p.m. The family was planning a trip to Hawaii, and Amber wanted to reassure Wiederrich they would make an itinerary for the trip. Nothing in the conversation caused Amber any concern for Wiederrich’s wellbeing.

3 The next day, February 13, 2016, Johnny arrived at Wiederrich’s house around 7:15 a.m. He entered the code to open the front door and went in. He walked into the kitchen and found Wiederrich lying on the floor in a large puddle of blood. She was cold to the touch. Johnny called 911. A knife was lying next to Wiederrich. Her hands were tied behind her back. It appeared to Johnny that someone had gone through Wiederrich’s belongings. He noticed that Wiederrich’s wallet was open on the counter and her purse had been dumped upside down in the kitchen sink. In the bedroom, a jewelry box was upside down on the dresser, and drawers were pulled out. Police officers found no signs of a forced entry. The garage was closed, and the side gate was locked. There was no indication anyone had been in the backyard. In the kitchen, Wiederrich was lying on the floor wearing light colored pajamas. She had been gagged with a blue handkerchief that was tied around the back of her head. Her hands were bound behind her body by zip ties, six of which were recovered at the scene. A knife was lying a foot or two away from Wiederrich’s body. It was a kitchen- style knife approximately 13 inches long. It had an eight-inch serrated blade and a wood handle. Wiederrich appeared to have multiple stab wounds in her chest. Officers found small traces of blood throughout the residence, but there were no signs of a struggle. Records from Wiederrich’s alarm company showed that on February 12, 2016, the day of the murder, Wiederrich’s front door was opened and closed at 6:35 p.m. and again at 6:54 p.m. There was no activity in the house until the front door was opened the next morning at 7:19 a.m., which was around the time Johnny had arrived at the house. After learning of Wiederrich’s murder, Amber called Katrina and relayed the news. Katrina became very upset. Katrina testified that on the day she received the news, she noticed that defendant’s hand had skin tears and “was pretty scratched up, beat up.” A few days later, Katrina and defendant brought some food to Amber’s house. Defendant, sitting with his hands crossed, consoled Amber and tried to cheer her up.

4 Amber noticed that defendant had a large sore on his right forefinger that looked as if he had rubbed a blister raw. When asked what had happened, defendant said it must have come from driving his car, and then he covered his hand back up. The evening after the murder, Wiederrich’s son William went through his mother’s house to see if anything was missing. Wiederrich had owned two guns: a revolver and a .25 automatic Raven. William could not find the guns in the house. Within a week of the murder, Amber was allowed to enter Wiederrich’s house. She noticed that a jewelry box she had given to Wiederrich for Christmas had been emptied.
