Videos have finally been released from the day a Las Vegas teen attempted to rape and strangle his teacher before attempting to slash her wrists.

The officer can be heard seeing who he believes is Garcia-Martinez and saying, “The suspect may have been seen, he sees the suspect right now outside his house.”

“Hey driver, turn off the car. Turn off the car. Jonathan gets out of the car. Do you know why we are here? a CCSDPD officer added after finding the teen in the car.

Dressed in different clothes than before, he answers “no” before being arrested.

Details of what happened in the classroom and outside the camera’s view were detailed during the trial.

Inside the room, the teen waited until the teacher’s back was turned before attempting to strangle her with “rope or rope.” He then slammed the girl’s head into the table, causing her to lose consciousness.

When the victim woke up, her pants and underwear had been pulled off. Martinez-Garcia doused her with something, saying he was going to set her on fire, and then pushed a bookshelf onto the woman, which he then sat on.

Sade told the judge she believed she would die during the horrific ordeal, which would leave her covered in bruises. At her sentencing hearing, Sade said she was “imprisoned” mentally and physically.

“It only makes sense that he too should be in prison for as long as possible,” she said, according to the report This was reported by the Las Vegas Review-Journal.

Martinez-Garcia was sentenced in Vegas Regional Justice Center after pleading guilty to attempted murder, attempted sexual assault and battery with a deadly weapon resulting in substantial bodily injury.A victim with trauma and multiple injuries.

Clark County Circuit Court Judge Kathleen Delaney sentenced Martinez-Garcia to a minimum of 16 years in prison, which could be extended to a maximum of 40 years. Associated Press reported.

Prosecutors asked the judge to sentence him to a minimum of 22 to 55 years behind bars. But in her sentencing Judge Delaney said she “weighed the seriousness of the offense against other factors”.

The brutal attack occurred after Martinez-Garcia came to his teacher’s classroom after school to discuss his grades. Police said he locked the classroom door before severely beating her.

The teacher told police she asked Martinez-Garcia why he attacked her and he responded that he “didn’t like teachers” and was “getting revenge.”

During the attack, Martinez-Garcia tried to slit the teacher’s wrists and told her, “Can’t you die already?”

He initially told officers he “blacked out” and didn’t remember the attack, but later admitted he remembered trying to strangle her.

Images of some of the brutal injuries Sade suffered were shown in the courtroom.

Sade recalled: “He beat me so hard that I couldn’t fight.”

“I woke up one day to find myself trapped under heavy shelves that he had toppled over me in a way that took my breath away and crushed me almost to death,” she recalled.

“I truly believed with all my being that I would die right here, under these shelves.”

Sade’s mother told the judge that her daughter used to be an outgoing woman, came from a family of educators and moved to Vegas to start her first teaching job.

But since the attack, she has found it difficult to leave the house due to ongoing physical and mental health complications.

“For the rest of her life, her last memory of teaching will be this student trying to kill her,” Sade’s mother told the judge.

Prosecutors said the teacher remembers Martinez-Garcia repeatedly saying, “Why don’t you die?”

Sade told the judge she did not return to her teaching job after the attack because she felt mentally and physically “imprisoned.”

Martinez-Garcia fled after the attack and took the keys from the teacher. The instructor was later found by a school employee who called 911.

The teenager was arrested shortly after by school police as he headed to an awards ceremony at school.

The judge rebuked Martinez-Garcia, telling him that such an attack on a teacher was completely unacceptable.

“This is the most heinous kind of crime there is,” the judge said.

His mother described him as a “good student”. She said he had not been diagnosed with any medical or mental health problems,” but told police he had seemed “depressed and disconnected from reality” in recent months.

In the arrest report, Martinez-Garcia described detectives attacking his teacher.

He said: “I don’t know why I attacked her, she was kind to me.”

Martinez-Garcia’s public defender, Ty Gaston, argued that his behavior was caused by serious side effects of the asthma drug Singular, which caused mood changes, nightmares and hallucinations.

Singulair’s maker, Merck, is facing multiple lawsuits alleging the company concealed a link between its asthma drug and serious mental health consequences for patients.

Chief Deputy District Attorney William Rowles said Wednesday he did not believe a side effect of the medication was a valid reason for the attack.

“I firmly believe that there are still certain crimes and certain acts that require punitive punishment,” he said.

In April, Martinez-Garcia took a plea deal that avoided trial on the after-school assault charge after he pleaded guilty to attempted sexual assault and battery with a deadly weapon resulting in serious bodily injury.

Other charges against him were also dropped, the Associated Press reported.

At his sentencing, Martinez-Garcia, dressed in dark blue prison clothes, apologized and said he was sorry for what he had done.

He told the courtroom he blamed no one but himself and said he was willing to “accept the consequences.” KSNV reported.
