The Escuinapa civil protection chief was shot dead in the centre of the small Sinaloa town on Sunday afternoon, 11 October, hours after he had toured shelters set up for Hurricane Simon. Jesús Francisco López Bibriesca was the official in charge of emergency response in Escuinapa, Mexico’s southernmost Sinaloa municipality, on the border with Nayarit. His killing matters to foreigners because it lands in the same southern corridor as Mazatlán, a resort and cruise port that draws many American visitors, just as a major hurricane threatens the coast.
Mayor Víctor Manuel Díaz Simental confirmed the death, according to El Heraldo de México. He said he received the news at about 3:30 p.m. local time. No arrests and no motive had been announced by Monday morning.
How the Attack Unfolded
Local reports agree on the outline. López was driving a private vehicle from his home when armed men intercepted him on Calle Francisco Pérez, between 16 de Septiembre and Melchor Ocampo streets, in the town centre, the Sinaloa newspaper Noroeste reported.
His body was left in the middle of the street with a gunshot wound to the head. Red Cross paramedics arrived but he was already dead. Noroeste said authorities found 9mm shell casings at the scene.
Municipal police, state police and soldiers responded but did not locate the attackers, El Universal reported. Staff from the Sinaloa state prosecutor’s office, the Fiscalía General del Estado, gathered evidence at the site, according to TV Azteca.

A Storm Official Killed Mid Emergency
López had taken the job only in July. On Sunday morning he joined the mayor on inspections in Teacapán, Isla del Bosque and other parts of the municipality. They checked shelters, low-lying areas and drain clearing ahead of Simon.
“He was a very hard-working, very modest person. I honestly do not understand what is happening,” Díaz Simental told local reporters, as quoted by El Heraldo de México.
The municipal civil protection council had met on Thursday, 8 October, to prepare shelters and monitoring of low areas for the storm, Revista Espejo reported. The killing removes the Escuinapa civil protection chief at the moment his role matters most. The municipality has not said who will take over.
Simon remains a serious threat. At 11 p.m. local time on Sunday, the US National Hurricane Center placed the Category 3 storm about 140 miles west-northwest of Manzanillo, with winds of 115 mph. It expects Simon to move inland over west-central Mexico around midweek and weaken quickly after that. A hurricane watch runs north of El Roblito to Bahía Tempehuaya.

Governor Graciela Domínguez Nava suspended Monday classes in seven municipalities, including Escuinapa and Mazatlán, as a precaution, Ríodoce reported.
A Pattern of Attacks on Local Officials
The killing is the latest in a run of attacks on Escuinapa’s public servants. On 31 March, gunmen shot the municipal deputy police chief, Esteban Gutiérrez Mazariego, and three of his escorts on the Mazatlán to Tepic highway, El Universal reported. A municipal police officer was shot dead on 8 April as he returned home after his shift, TV Azteca reported.
On 30 August, the deputy director of municipal traffic was killed. Revista Espejo said López is the second town hall official shot dead in less than two months. El Universal counts him as the fifth public official killed in Sinaloa this year.
Sunday was also violent in nearby Mazatlán. Ríodoce counted seven killings in the city that day. One man was shot at about 6 p.m. in the car park of the Galerías Mazatlán shopping centre in the Marina district, an area of hotels, restaurants and schools. Families inside panicked as gunmen chased him.
Ríodoce noted that about 10,000 personnel from federal, state and municipal forces are deployed in Mazatlán. That presence has not stopped the shootings. Last week the city’s prison also erupted, as covered in Mazatlán Prison Riot Kills 10, Injures 16.
The backdrop is a feud inside the Sinaloa Cartel between La Mayiza, loyal to Ismael “El Mayo” Zambada, and Los Chapitos, the sons of Joaquín “El Chapo” Guzmán. It began in 2024 after Joaquín Guzmán López allegedly kidnapped Zambada and delivered him to US authorities. Research cited by Zócalo says the fighting has moved from Culiacán towards Mazatlán and the municipalities bordering Nayarit. Investigators have not linked Sunday’s killing to either faction.
What It Means for You
For American travellers, the State Department’s Mexico advisory keeps Sinaloa at Level 4, “Do not travel”, and asks Americans to follow the same limits on movement as US government staff. Read those limits for Mazatlán before you go; small towns such as Escuinapa carry the same state-wide warning.
Visitors already in Mazatlán face two separate risks this week: the storm and street violence. Follow local civil protection channels and Mexico’s national weather service, and check flights and cruise schedules before moving. InSight Crime analysts cited by Zócalo describe the violence as more selective, but Sunday’s mall shooting shows bystanders can be caught nearby.
For investors and companies with staff in the region, repeated attacks on officials during emergencies raise questions about how well local government in southern Sinaloa can function.
What Is Not Known
Police have not named suspects or a motive. The Sinaloa state prosecutor had not published a statement by Monday morning. Local reports differ on the spelling of the victim’s second surname and on his middle name. Escuinapa has not said who now runs its civil protection office, or whether storm plans have changed. It is also unclear when Simon will make landfall and how hard it will hit southern Sinaloa.
