OGDEN - A 51-year-old Ogden man killed by police early Thursday was armed and ready for officers when they forced their way into his house, police said.
William Louis Florez pointed a gun at SWAT team members from the Ogden and Layton police departments, prompting two officers to open fire on him, killing Florez as his brother looked on, said Lt. Scott Sangberg.
“He was up and he was armed,” Sangberg said.
Police have not described the gun or said whether Florez fired at officers. SWAT officers entered the house, at 368 28th St., about 1:40 a.m. and opened fire on Florez within seconds, he said.
One Layton and one Ogden officer - whom police have not identified publicly - have been placed on administrative leave pending an investigation into the shooting by Weber County homicide detectives and internal reviews by the Ogden and Layton police departments.
Florez - a convicted killer - was suspected of dealing drugs and guns and had been considered by police to be armed and dangerous, Sangberg said.
When applying for the no-knock warrant, police rated Florez a 72 on a 100-point threat scale, Sangberg said.
“That’s one of the highest [ratings] I’ve seen in my career,” said Ogden police Lt. Tony Fox.Also Thursday morning, SWAT officers entered a house down the street from Florez and arrested a woman they said was dealing drugs with him.
Myra K. Carlisle, 48, was booked into the Weber County jail on suspicion of distributing drugs.
The searches were part of a two-month investigation by the Weber-Morgan Narcotics Strike Force, Sangberg said.
In the 1970s and ’80s, Florez committed numerous violent crimes, according to Tribune archives.
He barricaded himself in a home and exchanged gunfire with police in 1976. Soon after his parole for those crimes, he returned to prison for hitting his father-in-law over the head with a bottle.
Then, in 1981, he was charged with raping, robbing and cutting a woman, a case he settled by pleading guilty to aggravated assault.
Five years later, Florez fatally stabbed Stephen Myers, 29, twice in the chest after finding the man in bed with his girlfriend. Florez was convicted of capital murder, but the jury decided against the death penalty.
The Utah Supreme Court later reversed the conviction and ordered a new trial. Florez pleaded guilty in 1990 to manslaughter and possession of a dangerous weapon and was sent to prison for up to 20 years.
At his first parole hearing later that year, Florez told the board he was a changed man and that he had promised his mother before she died that he would go straight and help take care of their family.
He was released from prison in June 2006 and, according to the state court system, was not charged with any crime since.
Carlisle’s criminal history since 1996 consists of three misdemeanor convictions, two for theft and one for possession of drug paraphernalia. She was sentenced to fines and probation.
