A California college student, Matthew Boulet, was sentenced 15 years in prison after he repeatedly stabbed both his adoptive father while home on summer vacation.

Boulet did not contest the two counts of attempted murder.

He also admitted to cause great bodily injury during the attack.

The act was triggered by an argument between the three family members on Jul. 24, 2018, according to a Daily News report.

Prosecutors said Boulet whipped out a pocket knife at one point and stabbed one of his fathers in neck, torso, arms, face, and arms, according to earlier reports of the Los Angeles Times.

The second man attempted to intervene. Boulet then stabbed the second man as well.

Boulet was 21-years-old at the time.

Boulet's adoptive dads were both in their 50s and survived the violent incident.

Los Angeles Police told at the time that Boulet was very nonchalant when he had stabbed his two father and that he got a wound from doing so.

The police also said that he was very calm about it.

The Los Angeles District Attorney announced on Thursday that Boulet was sentenced 15 years and four months in prison.

Boulet is 23-years-old at the time of his sentencing.

The Incident

Boulet was visiting his adoptive family in Sherman Oaks over the summer when he stabbed his adoptive fathers.

The attack occurred before 1 a.m. in the 4600 block of Burnett Avenue, according to LAPD spokeswoman Norma Eisenman.

Boulet's mother then called the police and reported the incident, Eisenman said.

The second man was also described as Boulet's father.

One person suffered cuts to the face, according to officials.

Police said the attack happened during a family argument.

"Whenever something in the home gets so far out of hand where violence is the option, there's a lot to be concerned about," LAPD Lt. Mike Kozak was quoted in a Los Angeles Times report.

Kozak said that Boulet did discuss the incident with the police and let them know that he was involved with the incident.

Kozak added that there is no outstanding suspect.

California Crime Rate

A fact sheet that was released in September by Center on Juvenile and Criminal Justice shows that the state's crime rate fell by three percent in 2019 from the year before.

This shows it has reached its lowest level since the state began collecting the statistics 50 years ago.

Crime rates in California have continued to reduce steadily during the past decade.

These data suggest that crime is falling not rising during an era of progressive policies and important reinvestment in communities.

However, the COVID-19 pandemic seemed to have changed the crime rates.

In a report done by Public Policy Institute of California, it showed that the reported number of larcenies and residential burglaries remain lower before the pandemic.

However, car thefts and commercial burglaries have increased.

Some violent crimes in California's major cities went up.

These cities are Los Angeles, Oakland, San Diego, and San Francisco.
