Jose Evis Quintana, the father of alleged 16-year-old killer Alec McKinney was once jailed for 15 months for domestic violence against Alec's mother and 'menacing with a weapon'.

McKinney has been charged alongside his friend Devon Erickson of killing one student and injuring eight others at the school close to Denver, Colorado.

Records show Quintana, 33, who was also deported twice, had a string of arrests in Colorado dating from 2008 to 2017.

Court papers show that despite Quintana terrorizing Alec's mother Morgan Lynn McKinney, 32, he managed to convince her to marry him in 2009, a year before he was first deported.

Quintana, 33, who admitted to having a history of drink and drug problems, was sent back to his native Mexico on December 9, 2010.

Alec had posted a message on social media about missing his father, just 11 days before the Tuesday May 7 shooting allegedly committed by McKinney and 18-year-old Erickson.

Transgender McKinney, who was born a girl called Mya, had turned 16 on April 14 and wrote on twitter on April 26: 'My mom talking to me about how she hates the new alec. Mom: I miss my Alec can you find him for me. Me: I miss my dad can you find him for me.'

Records at Douglas County District Court in Castle Rock, Colorado show Quintana had been jailed for 15 months in August 2009 for 'menacing with a weapon' and domestic violence against hairstylist Morgan.

Quintana and Morgan had Alec, born Mya Elizabeth, on April 14, 2003.

In January 2007 the couple had a son and in July 2008 they had a daughter.

But just two months later, on August 22, 2008, 5ft 10ins tall Quintana was charged with attempting to kidnap, 'menacing with a weapon', and failing to stop for police.

He was jailed on February 3, 2009, pending his trial, when he failed to see a court official.

Court papers said Quintana 'wishes to stay in custody since he has a problem with drugs and alcohol'.

The court agreed and also allowed Quintana to have supervised visits with Alec and his siblings in jail, on condition Morgan was not present.

On July 29, 2009, with Quintana in jail pending his trial, Morgan successfully gained permanent custody of their three children.

On September 2009, Quintana was sentenced to 15 months in prison when all the charges against him, apart from 'menacing' Morgan with a weapon, were dropped. He was also ordered to undergo domestic violence counseling.

Despite the sentence and the crimes Quintana committed against her, Morgan married Quintana in Castle Rock on November 28, 2009.

Qintana was then deported and sent back to Mexico on December 9, 2010.

In divorce papers filed by Morgan on November 19, 2014, Morgan described how Quintana 'has been traveling illegally between Colorado and Mexico' since the deportation.

Morgan was never able to serve her husband with papers but the court granted her a divorce on May 11, 2015.

On December 27, 2016, police in Castle Rock learned a warrant had been issued against Quintana in New Mexico for domestic violence.

They found him at a house in Castle Rock and arrested him for being a fugitive from justice. He was jailed pending his extradition to New Mexico.

Quintana never made it to New Mexico. On April 21, 2017, he was taken into custody by Immigration and Customs Enforcement (ICE) and deported.

On July 4, 2017, Alec posted on his twitter account 'And I wonder why my dad left'.

Alec may have been the victim of bullying at the school. On January 25, 2019, he posted on twitter: 'F**K stem kids i swear to f*****g god.'

It has been revealed five months before the shooting, a district official urged the school's executive director Penelope Eucker to investigate allegations made by a mother who was concerned that student bullying could lead to the next 'Columbine'.

The December 19 letter said the anonymous parent had raised 'concerns about student violence due to a high-pressure environment'.

It added that the mother had told Douglas County School Board of Education Director Wendy Vogel by telephone that 'many students are suicidal and violent in school. Several students have reported sexual assault and nothing is being done.'

On July 4, 2017, Alec McKinney wrote about his father leaving. Jose Evis Quintana had been deported by ICE agents on April 21 2017

The letter referenced an alleged bomb threat and 'an extremely high drug culture at STEM.

The parent had said she was worried about a repeat of what happened at Columbine High School, where 12 students and one teacher were killed, about five miles northwest of the STEM school.

The school hired a lawyer and told parents on February 1 it was looking at taking legal action against the unnamed mother who had made the accusations.

In an interview with CNN, the mother, who still wanted to remain anonymous pending legal action, said: 'When you don't listen to parents' concerns, when you don't support teachers' concerns, when you don't give teachers the kind of training that they need or the support that they need.

'Those are the elements that we need for the perfect storm, for something like a Columbine, or some kind of imminent threat to our children's safety in the school, whether it be a bomb or an active shooter, or a suicide.'

It is unclear what may have spurred Erickson, a keen drama student, to allegedly kill his classmates.

Friends told DailyMail.com he had recently split up from a girlfriend.

He was a keen fan of the television zombie show The Walking Dead. In 2014 he told friends he had applied for a role on the series and said his idol was actor Chandler Riggs, who plays Carl Grimes.

Just hours before Tuesday's attack Erickson and McKinney allegedly broke into the gun cabinet at Erickson's parents home.

At 150pm local time, they entered the middle school portion of the K-12 academy and began shooting.

Students managed to overpower them but not before the pair had shot eight and killed Kendrick Castillo, an 18-year-old student who had attempted to stop them.
