Police Chief Michel Moore Saturday announced the arrest of a convicted felon suspected in the murders of three homeless men in Los Angeles this week.
Moore said the same suspect, 33-year-old Jerrid Joseph Powell of Los Angeles, was already in custody in the follow-home killing of a county employee in San Dimas.
A handgun recovered from Powell’s vehicle was used in the three homeless killings, Moore said. “Our detectives worked closely with sheriff’s investigators and our forensics services overnight. The result of their work has positively identified the handgun recovered from Mr. Powell’s car as being the murder weapon of our three homicides,” he said.
Los Angeles County Sheriff Robert Luna said members of the Beverly Hills Police Department conducted a traffic stop of Powell’s vehicle Wednesday night, and Powell was arrested early Thursday.
Luna said the vehicle was linked to Powell after the San Dimas killing, which occurred just before 7 p.m. Tuesday in the garage of a home in the 1800 block of Hawkbrook Drive.
The first homeless killing occurred around 3 a.m. Sunday in the 800 block of West 110th Street, followed by another at about 5 a.m. Monday in the 800 block of East Seventh Street, and another at 2:30 p.m. Wednesday at South Avenue 18 and South Pasadena Avenue, Moore said.
“Each of the victims were in an open area, be it a sidewalk or alley, they were alone,” Moore said previously. “We believe a single individual approached each one and shot and killed each one as they slept. The investigators have gathered physical evidence as well as video images and we’ve identified this possible male lone individual as well as a vehicle.”
According to the chief and the county medical examiner, the victim in Sunday’s shooting was Jose Bolanos, 37. Killed on Monday was 62-year-old Mark Diggs. The victim in Wednesday’s shooting was a 52-year-old man, but his name was being withheld pending notification of relatives.
On Tuesday, Nicholas Simbolon, 42, who worked as a project manager in the Los Angeles County executive office, was found by his wife inside his Tesla in the garage of the home, suffering from a gunshot to the upper body, according to witnesses and sheriff’s officials. Paramedics pronounced him dead at the scene.
According to Luna, surveillance video determined that Simbolon was apparently followed home from an electric-vehicle charging station in the 200 block of South Citrus Street in West Covina. The suspect approached Simbolon in the garage, stole some unspecified items, then “senselessly” shot him, Luna said.
The sheriff said investigators saw a vehicle of interest on surveillance video that was believed to be connected to the crime. The license plate number of the 2024 gray BMW 440i four-door was entered into an automatic reader system which led to the discovery Wednesday of the car near Santa Monica Boulevard and Rexford Drive in Beverly Hills, and police pulled the driver over, leading to his arrest.
“If we did not enter that plate into the reader system, this individual that we believe is responsible for at least four murders may have been out there and re-offended,” Luna said.
Luna said the gun found in the vehicle is also believed to be the one used to killed Simbolon. The sheriff said there was no known connection among the four killings, and no known relationship between Powell and Simbolon.
Powell was booked early Thursday morning on suspicion of murder and robbery. According to jail records, he was being held on $2 million bail.
Mayor Karen Bass lauded the involved agencies for their coordinated efforts to collar the suspect. “When we come together as a city and as a region nothing can stop Los Angeles,” Bass said. “We step up to challenges and we address them.”
Los Angeles County District Attorney George Gascón said his staff would be working on further charges Monday.
“My heart goes out to the family on this tremendous loss,” San Dimas Mayor Emmett Badar said in a statement Wednesday. “This is a priority investigation and I have faith in our sheriff’s office to properly investigate and bring this suspect to justice.”
Simbolon is survived by his mother, wife and two sons, ages 8 and 10, Luna said.
County CEO Fesia Davenport said Simbolon was a seven-year county employee, previously working at the county Superior Court, then joining her office in 2019. She said he was “key and instrumental in developing many software apps for the CEO’s office.”
Authorities said they can’t discount the possibility that Powell might have committed other crimes.
“Based on his criminal history, he didn’t just start doing this a week ago,” Luna said. Anyone with relevant information about Powell was urged to contact police or sheriff’s officials.
The killings struck fear among the city’s vast homeless population, and Mayor Karen Bass had urged unhoused people to avoid sleeping alone outdoors and instead seek company or shelter.
“This news is devastating to our city,” Bass said Friday. “Living on the streets we already know is dangerous. We already know that four to five people die each day on our streets from a range of causes, and violence is certainly one of them. But I want to be very clear about what we’re facing today. This is a killer who’s preying on the unhoused.”
The Los Angeles Homeless Services Authority activated its Augmented Winter Shelter Program in an attempt to provide additional safety for unhoused individuals, extending the program through Monday night. This means that in addition to traditional shelters at fixed sites in the city and elsewhere in Los Angeles County, the program will provide additional interim housing options, typically using motel vouchers.
