A man convicted of fatally stabbing a 71-year-old man in El Cajon was sentenced Tuesday to 43 years and eight months to life in state prison.

Gregory Daniel Carlomagno, 45, was convicted by an El Cajon Superior Court jury of second-degree murder and other charges for the Oct. 5, 2024, stabbing of Steven Barron.

El Cajon police said Barron was giving Carlomagno a ride to a store that evening, but the vehicle broke down on Benedict Avenue. As Barron attempted to get the car restarted, Carlomagno stabbed him, then fled the scene, police said.

Barron died later that night at a hospital.

At trial, Carlomagno testified that he acted in self-defense, according to sentencing documents filed by his defense attorney.

Police said officers responding to the stabbing spotted Carlomagno, who unsuccessfully attempted to carjack a vehicle from a motorist who drove off. Carlomagno then ran a short distance away but was arrested.

The Streamline: Thursday, March 12

TOP STORY

Starting today, the San Diego area will get a preview of summer as an unseasonable hot spell descends on the region, forecasters advised.

A strengthening high-pressure atmospheric system combined with winds out of the east will bring widespread record heat toward the end of the workweek. High temperatures will be 20 to 25 degrees above average west of the mountains on Thursday and Friday, according to the National Weather Service.

Maximum thermometer readings on those two days are likely to reach the low to mid-80s near the coast and the 90s across the inland valleys, tying or breaking records for those dates, the NWS reported. The East County highlands and desert locales will get less dramatic warming, up to about five degrees, meteorologists said.

LATEST WEATHER ALERTS FOR SAN DIEGO COUNTY

An NWS heat advisory for coastal and valley communities will be in effect from 10 a.m. Thursday to 8 p.m. Friday. The weekend will be less toasty but still unusually warm for this time of year, according to the weather service.

Next week, even hotter conditions are expected to arrive, bringing all- time record temperatures for March in some locations, forecasters reported.

Authorities advise the public to prevent heat-related health problems over the period by drinking plenty of fluids, staying out of the sun, limiting strenuous activities to early morning or evening, taking refuge in air- conditioned spaces if possible and checking in on potentially at-risk friends, relatives and neighbors.

BREAKING OVERNIGHT

The FBI is warning California law enforcement about a potential Iranian drone attack targeting the West Coast.

ABC News reported the FBI alerted police departments across the state in recent days that Iran – in retaliation for U.S. strikes – could attempt a surprise drone attack launched from a vessel off the coast.

As of now, federal officials said there is no specific or credible threat.

Gov. Gavin Newsom said Wednesday at a news conference that he’s aware of the apparent threat of Iranian drone strikes on California. He said when the war started, he activated the state emergency operations center.

“Drone issues have always been top of mind,” Newsom said.

“As it relates to drone strikes, we have been aware of that information,” he said. “We have been working collaboratively through the (operations center), which we established right after the war began — the State Operations Center. Working with the Office of Emergency Services, but also working locally to make sure we transmit any information that we have received.”

In a social media post, San Diego Mayor Todd Gloria said, “The City is aware of reporting indicating Iran allegedly explored using drones for potential attacks in California. There are no known threats to San Diego. SDPD is coordinating closely with regional, state, and federal partners, and we are prepared to respond to any emergency.”

The Rotary Club of La Jolla hosted San Diego Police Chief Scott Wahl at its March 10 meeting as he spoke about his team’s role in the community, pointing out that it does not include enforcement of federal immigration laws.

Meanwhile, the club is continuing its contributions to a fire station fundraising project.

Here’s a breakdown of the latest Rotary happenings.

Chief explains SDPD and ICE dynamic

Wahl discussed his department’s priorities and attempted to clarify the differences between its operations and those of U.S. Immigration and Customs Enforcement.

Wahl, who led SDPD’s Northern Division, which includes La Jolla, as a captain in 2021-22 and took over as chief in 2024 following the retirement of former chief David Nisleit, said he has three main goals for the department: Build trust, develop leaders and be efficient and effective with the resources allotted. Its overarching job, he added, is to provide stability and structure “when things are out of control and there’s chaos.”

Several questions from people at the meeting were directed toward the Police Department’s role — or lack thereof — in ICE operations.

San Diego police do not enforce federal immigration laws and are subject to state regulations. California Senate Bill 54 “prohibits SDPD officers from investigating, detaining or arresting people based solely on their immigration status,” according to the city of San Diego.

SDPD officers are not allowed to ask about immigration status, participate in immigration enforcement or assist with immigration arrests. They are responsible for answering calls for emergency help and providing information as available to elected officials about the details and circumstances of calls.

Wahl described the department’s role as “apolitical,” though he added it’s an increasingly fine line to walk.

“Obviously this is a very polarizing issue with many different views,” Wahl said. “I’m sorry the way this is impacting families and folks that have been in this country for many, many years. I wish there was something I could do to change that. But I am very cautious to make sure I’m not in my role creating or making this … Police Department a pawn in a political battle.”

“They [ICE] have their areas of responsibility, we have our areas of responsibility,” Wahl said. “Unfortunately, right now during this tough time, we all get painted with the same broad brush.”

Wahl told the La Jolla Light after the meeting that it’s unsurprising that immigration enforcement is a topic of local interest given San Diego’s proximity to the U.S./Mexico border.

“It’s a tough issue, and it’s really tough to be succinct and to the point [and] have people understand all the different layers,” he said. “I understand people want us to do something. And I want to be able to do something. But in many respects, there’s not much we can do.”

Wahl said he was unaware of any ICE-related calls SDPD may have received in La Jolla, though areas such as Linda Vista, South Park and Mission Valley have been affected.

Fire Station 16 fundraising

An ongoing effort to renovate San Diego Fire Station 16 on Mount Soledad in La Jolla continues to gain steam and is now about $45,000 from its fundraising target, Rotarian Cindy Goodman told the Light.

The city approved a Phase 1 revitalization plan shepherded by the La Jolla Sunrise Rotary Club to replace walls and doors in the station’s sleeping areas, along with other improvements.

The San Diego Fire-Rescue Foundation and the Rotary Club of La Jolla have teamed with Sunrise Rotary in an agreement that if the Rotarians come up with the money and materials for the project, the city will provide the labor.

The Fire-Rescue Department says Fire Station 16 was built in 1982 and hasn’t had any major renovations since, instead receiving small upgrades. Renovating the station will enable firefighters to have better sleep, privacy and living standards, project organizers say.

The overall funding target is $175,000. But with more than $130,000 collected so far, the clubs should be able to cover construction and temporary housing costs, Goodman said. Now they are awaiting city guidance on temporary trailers that meet requirements.

“The community has been wonderful about supporting the project to provide decent housing for our firefighters, and all those involved are very grateful,” Goodman said.

Kiwanis and Rotary joint meeting to feature S.D. council president

Less than a month after he held a town hall meeting at the La Jolla Recreation Center, San Diego City Council President Joe LaCava, whose District 1 includes La Jolla, is scheduled to deliver a city update at a Rotary Club meeting later this month.

The meeting, a joint effort including the Kiwanis Club of La Jolla, will begin at noon Tuesday, March 24, at the La Valencia Hotel, 1132 Prospect St.

Hot topics at LaCava’s March 4 town hall included area speed limits, city budget issues and continuing infrastructure projects. ♦
