Los Angeles DA failed to convict the man who killed two and injured six in Las Vegas stabbing

The man accused of stabbing eight and killing two in Las Vegas on Thursday walked free from another violent crime charge last year after the district attorney failed to prosecute in time.

Court documents exclusively obtained by DailyMail.com reveal that Guatemalan alleged undocumented migrant Yoni Barrios, 32, was charged in 2019 with criminal domestic violence by Los Angeles district attorney Jackie Lacey, who has since stepped down.

Had he been convicted, Barrios would likely have been imprisoned and deported and would not have been free to commit the senseless slaughter on the Vegas strip this week.

But then Lacey failed to bring the case to court in time, and after 90 days elapsed the judge was forced to dismiss the case under California speedy trial laws.

Barrios was also prosecuted for driving dangerously and without a license in Riverside, California in 2016.

After his arrest on Thursday Barrios told detectives he was from Guatemala and wanted ICE to take him home, according to a report released by the Las Vegas Metropolitan Police Department (LVMPD).

Sources at the Department of Homeland Security told Fox News they believed he is an undocumented migrant, and does not have a visa.

A criminal docket for Barrios obtained by DailyMail.com shows he was charged in July 2019 with criminally injuring a spouse, cohabitant or fellow parent in an act of domestic violence.

If charged as a felony, perpetrators can be sentenced to up to four years in prison.

Barrios’ docket says the alleged incident occurred on August 18, 2018.

Lacey filed the case a year later, but the first pre-trial hearing was left until more than two years later on April 8 2021.

The court documents say the case went to trial, but was dismissed the same day by the judge because it had languished in the court system for too long.

According to the California Penal Code, prosecutors must bring a case to trial within 60 days of filing an indictment for a felony.

If Barrios had been put on trial promptly after the case was filed in July 2019 and convicted, he could have faced up to four years in prison, and would not have been free to commit the alleged two murders and six attempted murders with which he was charged this week.

The US Immigration and Nationality Act also lists a domestic violence conviction as one of the key criteria for the deportation of an illegal immigrant.

During her tenure as LA DA from 2012 to 2020, Lacey styled herself as tough on crime and even pursued death penalty cases in the face of a moratorium from Governor Gavin Newsom.

But she came under fire from justice campaigners for her delay in prosecuting some prominent figures including West Hollywood Democrat donor Ed Buck, who injected multiple male sex workers with potentially lethal doses of drugs at his apartment.

She was also criticized by the Black Lives Matter movement for failing to prosecute police officer Clifford Proctor for shooting dead Brendon Glenn, despite a recommendation from former LAPD chief Charlie Beck.

Barrios has another criminal record in Riverside, east of Los Angeles. In April 2016 he was caught speeding and driving without a license.

He was given a citation and paid a fine.

According to his LVMPD arrest report, Barrios lived in Los Angeles and traveled to Vegas on Tuesday to stay with a friend, but when they reneged on the offer he headed to the strip and ended up attacking a group of showgirls to ‘let the anger out’.

One of the victims was Maris Digiovanni, 30, Westby’s coworker at Best Showgirls in Vegas, who died in her friend, Anna Westby’s, hands after they were approached by Barrios. 

‘He pulled up a knife and he showed it to us as if modeling it,’ she told the New York Post. ‘Before we could say anything at all. He grabbed the knife and he stabbed Maris in the heart,’ she said. 

The moment was so shocking to Westby, 26, that she didn’t even have time to worry about herself as she tried to apply pressure to Digiovanni’s wound. 

‘And another guy said, ‘Ma’am, you have a stab wound on your back.’ I said, ‘I know.’ Can you grab your shirt and apply it to my back while I apply this to her?’ 

After stabbing Digiovanni in the heart, Westby said the man slashed a fellow showgirl, Victoria Caytano. Westby said she and Digiovanni tried to run, but to no avail. 

‘Maris made it only about 15 feet before she collapsed,’ Westby told the Post. ‘And he came after me and stabbed me in the back, and he ran off.’ 

The showgirl’s boss, Cheryl Lowthrop, said her employees are still reeling over the incident as they mourned Digiovanni, who also worked as an elementary school teacher. 

Lowthorp has started a GoFundMe page to help her employees impacted by the tragedy and to cover funeral expenses and other costs for Digiovanni’s family.
