Post #75 on Page 3 of The Colt Forum link I posted above (I hadn't read that far) has details on this:
#75 · Nov 9, 2020
Found it. Nov 1, 1906 El Paso Times. It was a domestic situation, a Manuel Rodriguez killed his wife, barricaded himself, started shooting others. He owned a restaurant beside the El Popular saloon, adjoining. Officers climbed the roof, entered the saloon, and (by our photo) shot a fusillade of bullets for less than an hour at the restaurant. The door was battered in, and Rodriguez was dead on the floor with 4 bullet wounds.
"The four men who rushed the house and first gained entrance were deputy Sherriff George Briggs, police officer Tom Miller, Tom Powers, and constable Manny Clements."
The article is hard to read, very long and windy. But interesting points:
"The shooting attracted fully two thousand people, who crowded about...laughed in defiance of the edicts of police to keep back...."
"Officers declared....indiscriminate shooting by unauthorized persons and several of the officers delayed the taking of Rodriguez..."
"Officer Juan Para [actually Alderete] used a telephone pole near the restaurant as a breastworks..."
"An investigation showed that the post behind which the officer had been standing contained three bullets from the revolver of Rodriguez..."
from Post #76:
Four people died, Rodriquez, his wife, and a bystander 2 year old boy. 3 more were wounded. I've got the whole article, but it's pretty hard to piece it together to be readable, it's a PDF or two.
"hundreds of shots were fired....:
An outhouse that they thought he was in had 38 bullets from a .30-30 it it.
And from Post #106:
I covered this event extensively in my book, "Hell Paso: Life and Death in the Old West Most Dangerous Town," which was published last year.
