At least 14 people in northern Mexico were killed after two separate deadly incidents unfolded last week.

The first incident occurred around midnight on Thursday night in the Sinaloa state capital of Culiacán, where at least three gunmen allegedly attempted to kill a patient at a hospital.

“They tried to carry out a supposed execution inside, and there was an exchange of gunfire,” said Police Chief Gerardo Mérida, according to the Associated Press.

Two of the gunmen were killed during a gunfight with security guards. One doctor who worked in the hospital was fatally shot during the exchange of gunfire, Fox News reported. The third assailant died after allegedly turning a gun on himself.

The second deadly incident occurred on Sunday in Ciudad Madero, where a church roof collapsed during a baptismal service, leaving at least 10 dead and another 60 people injured.

Tamaulipas state Gov. Américo Villarreal said about 70 people were in the building when the roof collapsed, and “there are no indications of life inside the collapsed area” other than those already recovered by search and rescue teams.

“The most likely thing, I can’t affirm it 100%, is that there aren’t any more people trapped,” he said, per the AP.

Father Pablo Galván was outside the church when the roof collapsed.

“Unfortunately, the elderly and children were those who suffered the most, the ones who were most trapped, the ones who suffered the most deaths, I think,” Galván said, per the AP.

While authorities have not confirmed the reason why the roof collapsed, a state security spokesperson reportedly said that a structural failure was the most likely explanation.

Villareal pushed back on the assertion, claiming that despite the church’s age, it was “functioning and operating with no problem, with no sign of any defect.”

Rev. Ángel Vargas was working the mass at the time of the collapse. He said he was a “faithful believer” who thinks all people “die at the time that God decides,” according to The New York Times.

“Some are now gone and others of us remain,” he said. “Those who are gone, rest in peace. Those who remain, we’ll surely suffer the rest of our lives.”
