Police say two Utah men fatally shot possible would-be criminals a few miles apart over the weekend, but neither shooter is expected to face charges in a gun-friendly state that was one of the first to pass a "stand your ground"-style law more than 20 years ago.

In the first shooting, a man who holds a concealed carry permit intervened when a carjacker jumped into a woman's vehicle in Orem on Saturday morning. The perpetrator was shot while lunging for the bystander's gun, police say.

Hours later, a homeowner in Pleasant Grove shot a man who pounded on his front door in the middle of the night, climbed to a second-floor balcony and attempted to force his way in, police say. Detectives have since gathered evidence indicating the man was likely intoxicated and may have thought he was entering a nearby residence he shared with several roommates.

Prosecutors have yet to review the cases, but police and legal experts say the shooters will likely be cleared of wrongdoing, since Utah allows the use of deadly force in many circumstances.

"If a reasonable person objectively would have felt this woman's life is in jeopardy or his own life was in jeopardy, he's justified in using deadly force," said Greg Skordas, a Utah defense attorney and former prosecutor.

Utah's law was revised in 1994 to extend protections for use of deadly force in public without a duty to walk away — more than a decade before Florida passed its well-known "Stand Your Ground" law in 2005, said Laura Cutilletta, a Law Center to Prevent Gun Violence attorney. Since then, at least 30 states have enacted similar self-defense laws.

Cutilletta said it sets "a very dangerous normal" by making "people feel like it's kind of their job to do the work that police should be doing."

But gun-rights advocates say the weekend shootings show that Utah's laws allow responsible gun owners to protect themselves and others.

"We place a much higher value on innocent life than we do on someone who is committing a heinous crime such as robbery," defense attorney Mitch Vilos said.

He said the man who shot the carjacker in Orem should be covered by Utah law, since he was both stopping a forcible felony and faced an imminent threat of bodily injury.

Opponents, however, have said that deadly force shouldn't be protected in such a case, since the suspect was unarmed and carjacking convictions don't result in the death penalty.

The shooter "was someone who shot a defenseless man," the suspect's mother said in a statement released by police that didn't include her name.

The man who shot the trespasser on his balcony 5 miles away in Pleasant Grove should be on even more firm legal ground, Skordas said. Though laws about self-defense in public have shifted to grant more protections, gun owners have long had more latitude to defend themselves at home, he said.

Christian Chichia, 24, pounded on the front door of the home near 1700 W. 60 South at about 5:40 a.m. Sunday. The homeowner retrieved a handgun and went to the front door, but by then, Chichia — who lived in another townhouse in the same complex, but was a stranger to the homeowner — had climbed onto his second-story balcony.

The homeowner went to the balcony and cracked open the door to ask what Chichia wanted. Chichia allegedly tried to force his way in, and the homeowner shot him once in the chest.

Chichia was taken to Utah Valley Regional Medical Center, but died a short time later.

"We have interviewed all possible and potential witnesses, [and] there is a possibility that Chichia was confused and attempted to enter a residence where he thought he was welcome," Pleasant Grove Police Chief Michael Smith told The Salt Lake Tribune.

Smith stressed that in presenting the investigation's findings to the Utah County attorney's office earlier this week, detectives also had "thoroughly investigated" the perspective of the home's residents.

"The homeowners reported they were in fear [for] their safety due to the actions of the unknown person trying to force entry into their residence," the chief said.

Both cases will be screened by county attorneys to determine whether the shootings meet statutory requirements for self-defense.

Smith declined to say what specific recommendations his office had made.

For Vilos, the defense lawyer, firearms instructor and author of "Self Defense Laws of All 50 States," it should be an easy decision based on the information released.

"What message do we want to get to get across?" he asked. "Do want to tell innocent people that they are at risk of being prosecuted for defending themselves?"
