COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

THE PEOPLE, D085872

Plaintiff and Respondent,

v. (Super. Ct. No. SWF2102048)

BENJAMIN FRANKLIN WINKLE,

Defendant and Appellant.

APPEAL from a judgment of the Superior Court of Riverside County, John M. Davis, Judge. Affirmed. Sylvia W. Beckham, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Lance E. Winters, Chief Assistant Attorney General, Charles C. Ragland, Assistant Attorney General, Robin Urbanski and Flavio Nominati, Deputy Attorneys General, for Plaintiff and Respondent. Benjamin Franklin Winkle shot and killed a close friend and was convicted by a jury of second degree murder and possession of a firearm by a prohibited person. He was sentenced to 35 years to life in prison. During the trial, his former girlfriend, E.M., who was with Winkle just before his arrest, testified that Winkle threatened her and she feared for her life. On appeal from the judgment of conviction, Winkle argues that the trial court improperly admitted this testimony into evidence. Relatedly, Winkle contends the District Attorney committed prosecutorial misconduct by eliciting the testimony and asserting in his closing argument that Winkle threatened to kill E.M. Winkle also asserts that by failing to adequately object to E.M.’s testimony and the District Attorney’s closing argument, his counsel provided constitutionally ineffective assistance of counsel. As we explain, we reject Winkle’s arguments and affirm the judgment. FACTUAL AND PROCEDURAL BACKGROUND A. Prosecution Case Winkle owned several properties in California, including a rural property in Anza, which he used to farm marijuana. The victim, Michael Mendoza, was Winkle’s long-time friend and helped him take care of the Anza property. Mendoza regularly stayed at the property and Winkle came down from his home in Northern California every month or two to visit. The property was remote, but there were a few neighbors. R.H. lived down the hill from Winkle’s property and had known Winkle for about 15 years. T.S., another neighbor, lived in a trailer near Winkle’s property and had known Winkle and Mendoza for about five years. Four years prior to the murder, Mendoza asked T.S. to look after a .45 caliber firearm that was given to him by Winkle. The gun was wrapped in a plastic shopping bag and T.S. agreed to store the weapon in his trailer.

2 Winkle also owned a dog-breeding business with L.N., his ex-girlfriend and the mother of his young child. Winkle and L.N. were together about 10 years and separated about a month before the murder. When they were together they sold the dogs, Presa Canario and French Bulldog breeds, and shared the profits. As a result of the separation, their relationship was strained. At the time of murder, Winkle had some of the dogs in his possession and L.N. was trying to get them back from him, including a mother Presa Canario and her four puppies. On the morning of October 6, 2021, Winkle and Mendoza arrived at the Anza property after driving there from Northern California in Winkle’s minivan. They planned to pick up a BMW that was kept on the property for Mendoza to drive. Winkle also brought the four puppies with him and intended to take the dogs to Los Angeles to have their ears clipped. After they arrived at the Anza property, Winkle and Mendoza went to T.S.’s trailer around 9:00 a.m. T.S. saw Winkle drinking beer and testified Winkle was slurring his speech and appeared drunk. Winkle asked T.S. to return his gun and T.S. gave the gun back to Winkle still in the plastic shopping bag. Winkle also retrieved a truck from T.S.’s property that T.S. had borrowed. Shortly after, T.S. walked over to Winkle’s property and saw Winkle and Mendoza working on hitching a trailer to the truck. While helping Winkle and Mendoza with the truck, T.S. received a call from a friend who had run out of gas and needed help. T.S. left to help his friend. T.S. returned in his own truck about an hour later and saw that Winkle’s truck was stuck in the sand. Mendoza was on his hands and knees trying to get the truck out, and Winkle was standing over Mendoza yelling, “You ran over my dog. You killed my dog. You ran over my dog.” T.S. saw one of the puppies was badly

3 injured. Mendoza asked T.S. to go and get a high-lift jack to help free the stuck truck. T.S. walked away to look for the jack. As he did so, T.S. heard a loud pop, which he assumed was Winkle shooting the injured puppy to end its misery. After a 30-second pause, T.S. heard between six and nine more pops. When T.S. returned to the truck, he saw Mendoza’s lifeless body and Winkle standing over him with a gun in his hand. Winkle was waving the gun frantically, and said, “you’re not going to tell anyone, are you?” T.S. thought Winkle was going to kill him. Winkle asked T.S. to help him put Mendoza’s body in the back of T.S.’s pickup truck to bury Mendoza in the desert. When T.S. refused, Winkle began waving his gun again at T.S. and cursing. T.S. then ran over to his truck to get away. Winkle followed and took the keys out of T.S.’s ignition before T.S. could start the car. T.S. pulled out his phone to call 911. Winkle tried to wrestle the phone from T.S., but T.S. managed to hide it in his back pocket. Scared for his own life, T.S. offered to drive Winkle to Rancho Cucamonga or San Diego. Before they left, Winkle dragged Mendoza’s body to a nearby camper and covered it. T.S. and Winkle then drove off the property in T.S.’s truck. In an effort to get away from Winkle, T.S. abruptly drove onto R.H.’s property and into his car port. As the truck pulled up, R.H. came outside from his house. T.S. jumped out of the truck and frantically yelled, “Benny just shot Michael.” As Winkle got out of the truck, the gun fell out of his belt buckle onto the ground. T.S. yelled at R.H. to grab the gun. R.H. quickly picked it up and set it near his house. R.H. told the men to leave. T.S. then got back into his truck, drove away to where he could get cell phone reception, and called 911. Meanwhile, Winkle asked R.H. for the keys to R.H.’s car. When R.H. said no, Winkle fled on foot. Homicide detectives

4 arrived and collected the gun from R.H.’s residence. The gun’s 13-round magazine was empty. Seven shell cases were found at the scene of the homicide and the parties stipulated that these casings were fired from the gun R.H. recovered from Winkle. During Mendoza’s autopsy, law enforcement also recovered a bullet from his body that was fired from the same gun. In addition, Winkle’s and R.H.’s DNA was found on the firearm. The coroner determined Mendoza’s cause of death was multiple gunshot wounds. He was shot a total of four times. One gunshot entered through his neck and hit his brainstem, which on its own, was fatal. Another gunshot entered through Mendoza’s right armpit and exited through his left armpit, piercing both lungs. The third punctured his thigh. The fourth gunshot entered through the back of his right hand and exited his fingers— indicating a sharp downward trajectory consistent with a person holding out their hands to protect themselves. After Winkle fled, the police began a manhunt. Aerial units searched using night vision, but were unsuccessful. Later that evening, police tracked Winkle’s cell phone to Escondido. Surveillance footage showed Winkle emerge from the minivan he and Michael had driven to Anza in an In-N-Out parking lot, but he escaped apprehension.
