San Mateo man pleads not guilty in girlfriend's fentanyl overdose death
Prosecutors said Pedro Armando Arellano was a regular fentanyl user along with his 26-year-old girlfriend Adrienne Dahbour. On Jan. 4, less than two weeks before his 27th birthday, Arellano allegedly gave Dahbour fentanyl, which they then used together. Dahbour later went home, where she lived in a detached unit on her parents' property in San Mateo.
The following morning, Dahbour was found in bed by her mother, dead from a fentanyl overdose, the DA's office said.

According to prosecutors, the couple had a history of fentanyl overdoses. Arellano had allegedly overdosed on fentanyl three or four times, and Dahbour had previously overdosed twice. Narcan was administered in previous overdoses, saving her life, the DA's office said.
At the time of one of the defendant's overdoses, San Mateo Police Department officers warned him that he would be charged with murder if he supplied fentanyl to someone who died from it, the DA's office said.
In Redwood City Felony Court on Thursday, Arellano pleaded not guilty to second-degree murder and waived his right to a speedy jury trial.
Arellano remains in custody without bail. A preliminary hearing was set for April 28.

Xavier Hernandez death: El Paso DA gets investigation, likely to go to grand jury
An investigation into the death of Xavier Guadalupe Hernandez during an arrest on the side of a freeway is now in the hands of the El Paso District Attorney's Office. It will likely go to a grand jury to determine if criminal charges will be filed against police officers. Hernandez, 30, died in a controversial case recorded on an El Paso Police Department body camera video that raised criticism over how police handled what started as a call about a pedestrian on Interstate 10 and ended with Hernandez's death on July 13. More: El Paso medical examiner rules man who died in police struggle as a homicide El Paso District Attorney James Montoya, in an emailed statement on Wednesday, Aug. 20, said his office has now received the investigation conducted by El Paso police. "While the case is pending, we cannot offer any other comment about it specifically," Montoya stated. "However, it is the policy of the DA's Office to present all in-custody deaths and officer-involved shootings to a grand jury of El Pasoans for their review and determination of potential criminal liability." EPPD body camera video released this week showed Hernandez in an agitated state on the shoulder of the busy freeway in a situation that quickly escalated into a struggle as an officer repeatedly shocked him with a Taser. "Officer, what's your badge number?" Hernandez repeatedly yells in the video, which shows Hernandez stop breathing while handcuffed behind his back and held facedown on the asphalt by officers. An autopsy by the county medical examiner's office deemed Hernandez's death a homicide caused by "asphyxia due to chest compression during law enforcement subdual and restrain" with cocaine toxicity as a "significant" factor. DA: Grand jury to look at police deadly force cases Montoya, a Democrat, took office in January after defeating former Republican DA Bill Hicks in the November 2024 election. Montoya previously had an unsuccessful run for DA, losing to Yvonne Rosales in the 2020 Democratic primary. Rosales later ended up resigning from office amid accusations of incompetence and Hicks was appointed by Gov. Greg Abbott to fill in the remainder of her term. During the 2020 campaign, police brutality was a hot topic amid the George Floyd protests, Black Lives Matter movement and the COVID-19 pandemic. In 2020, Montoya said in an El Paso Times interview that incidents in which police use deadly force should be automatically investigated. "Whether that is a discharge of a firearm, some kind of chokehold, any type of deadly force, including a Taser, which I believe is deadly force, will be presented to an El Paso grand jury for their review for potential criminal charges," Montoya said in 2020.

S.F. man convicted of hate crimes in Richmond District synagogue shooting
A San Francisco man who fired blank rounds inside a Richmond District synagogue in 2023 was convicted this week of multiple hate crime counts, officials for the San Francisco District Attorney's Office said Wednesday. A San Francisco jury found Dmitri Mishin, 53, guilty of six counts of interference with religious worship — with hate crime allegations found true in each count, officials said. Mishin was also convicted of six counts of brandishing an imitation firearm during the incident at the Schneerson Center, a Russian-speaking synagogue, officials said. On the evening of February 1, Mishin entered the synagogue on the 2600 block of Balboa Street and began speaking Russian to a group of people, many of them elderly, who were attending a religious class. According to evidence presented at trial, Mishin removed a replica firearm from the inside of his jacket and shot blanks seven to eight times before saying something to the effect of 'say hello to the Mossad,' referring to Israel's intelligence agency. When investigators searched Mishin's residence, they located a jacket carrying the firearm that he used. It had been loaded with non-projectile firing rounds, officials said. Investigators also found video from a month before the incident — taken by Mishin — showing him burning an object in front of the Schneerson Center, officials said. On Mishin's social media, police found photos of him holding what appeared to be a grenade and wearing a military-style uniform with a bird symbol and a swastika on bottom. The photo was posted to his social media the day after he shot blanks inside the synagogue, they said. Rabbi Bentzion Pil, who leads services at the center, told the Chronicle that his feelings about Mishin's conviction would depend on what happened during the sentencing. The incident still looms large in his memory — and in the memories of his congregants. Although the rounds were blank, he said it was a 'miracle nobody got a heart attack, because everyone thought they were real.' After the shooting, Pil estimated the congregation lost 80% of its regular members, who he said were too scared to worship in person. Slowly, people started to come back, but the membership levels now are only at about 60% of what they were before the shooting. The dwindling of the congregation and expense of hiring a regular security guard have made operating a challenge, he said. 'Everyone should feel safe and secure in their place of worship, but as this case demonstrates, unfortunately that feeling can be taken away in a matter of seconds,' said Assistant District Attorney Abigail Adams, who prosecuted the case. 'I commend the victims for overcoming their continued fear and testifying at trial and I am grateful to the jury for their very careful consideration of the facts and law.' Mishin is currently in custody. His sentencing is scheduled for August 29.

Men targeted people in racially motivated paintball attacks, California cops say
Two men are accused of targeting people in racially motivated paintball attacks, California deputies say. A 22-year-old Highland man and 24-year-old Colton man were each arrested on a count of assault with a deadly weapon and a hate crime enhancement, the San Bernardino County Sheriff's Department said in an Aug. 19 news release. McClatchy News is not naming the men as they have not been formally charged. Deputies said the men targeted multiple people in Bloomington and Fontana 'over the past few months.' The pair are accused of approaching in a Chevrolet Silverado truck, then firing paintballs at the people while screaming racial slurs, deputies said. The alleged attacks left the individuals with 'injuries to their faces and bodies,' deputies said. Deputies from the two city stations worked together and identified the two men as suspects, the sheriff's office said. After getting search warrants, deputies said they searched the two men's homes and found evidence that linked them to the alleged crimes. Each was booked into jail and released on bail, jail records show. In an Aug. 20 email to McClatchy News, a San Bernardino County District Attorney's Office spokesperson said they are 'aware of the incident,' adding that 'the case is pending review for filing decision.' Deputies said there may be additional victims and ask for anyone with information to contact them at 909-356-6767. Fontana is about a 50-mile drive east from Los Angeles.
