Michigan school shooter Ethan Crumbley’s love rat mom Jennifer tells court she closed door on his messy bedroom to avoid cleaning it and admits his dental hygiene was so bad he had 13 cavities – but still claims she didn’t neglect him

Jennifer Crumbley hit back at claims she was a ‘negligent’ mother as she told the court she and her school shooter son were ‘close’ – but admitted he had developed at least 13 cavities because he barely had his teeth brushed and spent most of his time in a shy bedroom.

The mother’s claim that they were close came just a day after her extramarital affair was revealed in court, as prosecutors argued that she was focused on her tryst with a fire captain over her troubled son.

She took the stand in her own defense Thursday as prosecutors closed the manslaughter case against her, where she faces up to 60 years in prison in the first case of a parent charged in a student’s school shooting.

She insisted her son Ethan – who is now serving a life sentence without parole – ‘can go at her with anything’ hours after she broke down in tears as her son’s final diary entries were revealed.

The disturbing diary entries seemed to contradict her claims that they were ‘close’, as Ethan wrote that ‘my parents won’t listen to me about help or a therapist,’ and ‘I have no help for my mental problems and it cause me to shoot at the fucking school.’

Her testimony came after a detective also broke down during the emotional hearing when talking about the four young victims in the school shooting.

Appearing in tears on the stand, Jennifer said speaking in front of others was her ‘biggest fear’, and began her testimony with warm memories of her ‘normal’ family life before the tragedy.

She said that Ethan’s school life was a struggle, as he could not concentrate on any subject but history, and “our biggest problem was that (Ethan) was missing assignments.”

When asked if she ever looked through Ethan’s text messages or internet history, she said she never would and only ever looked through his ‘messy’ bedroom.

Jennifer faced backlash after she was found to have bought the 9mm pistol that Ethan used in the shooting, but she testified that it was meant to be locked with a ‘cable lock’ and only ever at a shooting range to be used.

She shared a ‘happy’ social media post from the day she took Ethan to the shooting range for the first time, saying that while she found shooting boring, it was a surprise to be asked by her son to spend time with him.

Crumbley recalled a time earlier in the year when she was called into her son’s school because he was looking for ammunition in class, which at the time she brushed off as “no big deal.”

Ahead of her testimony, Jennifer Crumbley broke down in tears as her son's disturbing diary entries were read to the court on Thursday, in which he claimed his parents ignored his pleas for help.

In one diary entry shown on Thursday, Ethan wrote: 'I have no help for my mental problems and it's causing me to skip the f*cking school.'

The issue of Ethan’s school life came under scrutiny because on the day of the school shooting, he was caught by a teacher drawing disturbing images of murders and shootings on his homework.

Despite writing ‘the thoughts won’t stop help me’, both his parents refused to take him home and left him at school, where he secretly carried a handgun in his backpack .

At the time, Jennifer claimed she was too busy at work to take him home, but questions were raised about whether she had been having an affair with a local fire captain instead – a revelation that only came to light on Wednesday.

Fire Captain Brian Meloche testified Wednesday that Crumbley told him she could sneak out of work in the morning to meet him.

He added that the two of them would usually conduct their secret trysts on weekday mornings in a parking lot across the street from her work — although Crumbley testified that they would only meet once a week maximum.

Jennifer Crumbley's former boss Andrew Smith testified Wednesday that she would have been allowed to leave work if she had to take care of her son, contradicting her statements to police that she had to work because she was keeping Ethan in school.

Jennifer Crumbley’s former boss Andrew Smith testified Wednesday that she would have been allowed to leave work if she had to take care of her son, contradicting her statements to police that she had to work because she was keeping Ethan in school.

The actions Jennifer took on the day of the shooting took center stage in her trial this week, as prosecutors allege she played a role in preventing Ethan from carrying out the shooting.

When she and her husband James – who faces the same charges and will be sentenced in March – were called into the school, they said they were too busy with work.

Aside from claims that she may have been with Meloche, Jennifer said she would not be able to watch her son that day because she had to work – a claim contested by her former boss.

Andrew Smith, who fired Crumbley in the days after her son’s school shooting, took the stand Wednesday to insist that she would be allowed to leave work for the day if she said she had to take care of her son.

He added that if she had to bring Ethan to work with her, that would be allowed as well.

When she returned to work after the harrowing meeting, Smith testified that Jennifer Crumbley rushed down the hall from their workplace later that morning, yelling about an active shooter report at her son’s school.

As she then left work, Crumbley texted her boss that ‘the gun was gone and so were the bullets’ in her house, which he said he was ‘surprised’ to be told by the mother.

In another text shown in court, Crumbley told her boss: ‘I need my job. Please don’t judge me for what my son did.’

Smith testified that Crumbley was fired from her job days after the shooting, as she and her husband apparently tried to evade police by hiding in Detroit. Her lawyer argued she fled because of threats from the public about her son’s actions.

James Robert Crumbley was also charged in the shooting.

While investigating Jennifer’s actions in the aftermath of the shooting, it was revealed Thursday that she and her husband emptied their son’s bank account on the day of the shooting, withdrawing $3,000 and leaving just 99 cents in .

In the days after the shooting, the couple apparently tried to flee while police sought them for questioning, withdrawing another $6,000 from two other accounts, according to testimony from Oakland County Sheriff’s Office Lt. Timothy Willis.

The couple stayed at several hotels and bought new phones, after theirs were seized by investigators, before finally hiding out in an art studio in Detroit.

Jennifer’s lawyers argued she was not trying to escape custody but feared for her life after threats were allegedly made following her son’s crime.

Footage of their dramatic arrest in the studio was shown to jurors the day before, showing the furious moments they were arrested.
