A California cannabis industry worker was found guilty on Wednesday of murder and additional charges in connection with the brutal killing of a marijuana and tech entrepreneur. The entrepreneur, who had allegedly fostered a hostile and torturous work environment, reportedly forced employees to do pushups to receive their paychecks. Prosecutors stated that the worker, along with three accomplices, murdered the multimillionaire CEO at the very location where this alleged mistreatment took place.

“It’s fitting where they chose to take him,” said Santa Cruz County Assistant District Attorney Michael McKinney during closing arguments earlier this week, referring to the marijuana farm where 25-year-old Kaleb Charters killed CEO Tushar Atre. The Los Gatan reported that Charters, along with his brother Kurtis Charters and brother-in-law Stephen Lindsay, had been involved in the crime. Both Kurtis Charters and Stephen Lindsay were convicted earlier this year. A fourth suspect, Joshua Camps, is still awaiting trial.

Kaleb Charters, a former member of the U.S. Army National Guard, was found guilty on all charges related to Atre’s murder, including kidnapping and burglary, as reported by local news station KRON. During his trial, Charters recounted Atre’s demand for pushups as a condition for receiving paychecks.

“You guys are in the Army. Do 500 pushups,” Charters recalled Atre telling him and Lindsay, who was also a former National Guard member, according to reports from KRON.

Charters explained that he and Lindsay had lost the keys to a farm vehicle known as the “Monster Truck,” which infuriated Atre. This incident occurred just two months before Atre, who was based in Santa Cruz, was kidnapped, robbed, stabbed, and shot, according to the prosecution.

“Tushar was flipping out,” Charters testified, describing how he and Lindsay had recently planted hundreds of cannabis plants in the Santa Cruz Mountains, reportedly working 10 consecutive days from dawn to dusk for $200 a day. “He was going to cancel the checks,” Charters added.

Charters, Lindsay and Kurtis Charters allegedly recruited Camps to take part in a planned robbery of $1 million at Atre’s home. Things went wrong, though, when Atre managed to escape, according to prosecutors.

“Lindsay tackles him in the street,” McKinney said during closing arguments, according to KRON.

“Camps … started stabbing him over, and over, and over,” the prosecutor explained, while showing jurors photos of an SUV with Atre’s blood smeared all over it. “Tushar, for a second time, ran for his life. Kurtis grabbed him and threw him in this car.”

McKinney described how the men allegedly drove Atre to a Santa Cruz cannabis property to finish him off, with Lindsay yelling at him during the drive. “Why are you so mean to people?” Lindsay shouted, according to a confession that police say Camps gave after his arrest.

According to KRON, employees came forward and accused Atre of creating a toxic work environment to the point where staffers often “joked” behind his back about robbing or hurting him before Atre’s murder. They said he yelled at workers repeatedly, withheld and bounced their paychecks, and fired employees if he felt disrespected by them.

“They were humiliated in front of people,” Santa Cruz County Sheriff’s Detective Ethan Rumrill testified in late October about Kaleb Charters and Lindsay, according to KRON.

Sam Borghese, another cannabis worker, took the stand last month and accused Atre of being a boss who “pushed his employees very hard.”

“Did Mr. Atre invoke fear in his employees? (So) people would work harder for him?” Charters’ defense attorney, Thomas Brewer, asked Borghese.

“Yes,” Borghese replied.

Video of the alleged confession that Camps gave to police after his arrest was played in court during Charters’ trial, in which he described how the group allegedly murdered Atre.

“We zip-tied his hands, shoved a sock in his mouth,” Camps allegedly said. “I told him no one wants to hurt you, we are just here for your stuff. He kept saying, ‘Who are you guys?’ He didn’t know what was going on. … He was covered in blood. He was saying, ‘Please let me go.’”

Camps allegedly admitted to stabbing Atre in the neck after he tried to escape. He confessed to shooting him with an AR-15 rifle several times in the jaw and the back of the head afterward to put him out of his misery, according to police.

“He wasn’t going to last much longer,” Camps said on the video shown in court. “I knew he was going to die.”

Camps is still in custody, where he faces several counts ranging from carjacking to murder, online records show. He is facing charges of kidnapping, robbery, burglary, carjacking and first-degree murder. Lindsay and Kurtis Charters were convicted of murder and both sentenced to life in prison without parole.
