SAN DIEGO, CA — Crews are fighting a brush fire Monday near the Alpine area of San Diego County.

The fire sparked Monday afternoon south of Loveland Reservoir, near Sloane Canyon, according to Cal Fire.

“Fire is approximately 15 acres in size with a moderate rate of spread,” Cal Fire said on X, formerly known as Twitter. “Potential for 100 acres.”

No other information was immediately available.

Low clouds and fog are expected for some areas of San Diego County this week, with a few degrees of cooling and light showers over the mountains by mid-week, forecasters said Monday.

Downtown San Diego will see mostly sun Monday, with a high near 70 and a south wind up to 10 miles per hour. A high near 69 is expected in the downtown San Diego area Tuesday, with cloudy conditions in the morning and sunny conditions in the afternoon, according to the National Weather Service.

Along the coast, cloudy conditions are expected next week, with daytime highs in the mid-60s to low 70s. Inland valley areas are expected to be partly cloudy, with patchy fog and highs reaching the upper 70s.

The deserts are expected to be mostly clear and sunny, with highs reaching the upper 90s by Wednesday. Clear conditions are expected in the mountains throughout the week, with mild winds and highs in the mid-70s to low 80s.

Monday’s San Diego surf forecast includes a moderate-risk rip current, with surf height from 2 to 4 feet, water temperature from 61 to 64 and a mixed south swell from 190 degrees and west swell from 290 degrees.

No hazardous marine conditions are expected through Thursday, the NWS said.

The case of three surfers killed in Mexico “is eerily similar” to the murders of a San Diego couple in the same Mexican state four years ago, a private investigator said. 

Jay Armes III, who specializes in kidnappings in Mexico and works cases all over the world, immediately remembered Ian Hirschsohn and Kathy Harvey, a couple in their 70s who were slain in their longtime vacation home in El Socorrito, a tiny beach town in Baja California. 

Their bodies were dumped down a well, just like Australian brothers Jake and Callum Robinson, and American Jack Carter Rhoad, who were killed near Ensenada in Baja California during a carjacking over the weekend. 

“The story is they (the suspects) wanted the tires, not even the truck,” Armes said. “They burned the truck. That’s how little regard for life there is in these remote areas of Mexico. Anyone can be killed for anything.”

The San Diego couple were killed during a home invasion by a man who stole their bedding, according to a 2021 statement by Baja California Attorney General’s Office, which said they believed the burglar thought the home was empty. 

He was likely startled when he encountered Hirschsohn and Harvey before fatally stabbing them both and dumping their bodies, the Mexican prosecutor’s office said at the time.

They were ultimately found in a well “in the middle of nowhere,” Hirschsohn’s daughter, Ava Setzer, told The San Diego Union Tribune in a January 2021 story. 

That case, Armes believes, was on the minds of Mexican authorities, as their search for the missing surfers included area wells along the country’s northwest coast.

All three victims were found in a 50-foot well with gunshots to their heads, according to Mexican authorities. 

A fourth, unrelated victim – a woman whose name wasn’t released – was found with the U.S. and Australian victims. Prosecutors haven’t ruled out that the same suspects killed her. 

“I’m not taking away anything from good police work, but I think the idea to look in the well came from that case,” Armes told Fox News Digital. “At least they used their heads and made the effort to look. The extra body that was found was likely another one of their victims.”

Rhoad was slain just three months before he was going to tie the knot with his sweetheart, Natalie Weirtz, in August. Their wedding information was on Zola, which has since been taken down. 

“In the wake of the heartbreaking loss of Carter Rhoad, Callum Robinson and Jake Robinson, our hearts ache with grief for their families, friends and community,” Rhoad’s and Weirtz’s “close friend,” Aubrey Byers, wrote in a GoFundMe post. 

“Their presence brought immeasurable joy, love, and kindness to those around them, leaving a mark on our lives.”

Armes said there are so many beautiful tourist attractions in Mexico, but many destinations are either brutally violent cartel battlegrounds, or remote areas where people “just vanish.”

“And most are never found,” Armes said.

The surfers went missing last weekend and were found within days, a turnaround that’s almost unheard of in Mexico, according to Armes. 

Three suspects were identified, and two are being held on drug charges after law enforcement allegedly found them in possession of meth.

How quickly the dead surfers’ bodies were found sparked protests from locals and loved ones of the tens of thousands who are still missing. 

The Mexican government reported in March there were about 100,000 people missing, according to a report by The New York Times, but the United Nations believes that’s well under the real total.

“It is very difficult, except for high-profile cases like the one that just happened, for the authorities to immediately trigger the search,” Adriana Jaén told The Times. 

Jaén, a Mexico-based sociologist who helps families missing loved ones, said cases like the missing surfers are essentially salt in the wounds. 

“The message those of us who work on these issues get is that there are lives that matter, and there are others that don’t,” she said.

Two male suspects were allegedly caught with methamphetamines, according to Mexican authorities, and are being held pending that case. A woman, one of the suspect’s girlfriends, is also a person of interest. 

She allegedly sold out her boyfriend, Jesús Gerardo Garcia Cota, in court on Wednesday, according to a report by the BBC. 

She said Garcia Cota allegedly showed up at her house on April 28 and told her that he killed “three gringos,” a slang term that describes English-speaking foreigners.
