Two Florida teenagers were filmed laughing in the back of a police cruiser after being arrested for allegedly plotting to kill a classmate and use his blood in a twisted ritual honoring a dead school shooter.

Best friends Isabelle Valdez, 15, and Lois Lippert, 14, giggled and cracked jokes immediately after being taken into custody, according to video shown by prosecutors in Florida’s 18th Circuit court on Wednesday. 

‘This is such a bonding experience,’ Lippert told Valdez. ‘I love it.’

At another point, Valdez told Lippert that they could become ‘one of those lesbian couples now in jail.’

‘Hey, this is my b***h,’ Valdez joked she would tell other inmates. ‘Stay away.’

Valdez also said she had planned to do her makeup that morning ‘for the mugshot’ but couldn’t find any and lamented that she looked ‘horrible.’

Prosecutors said Valdez was obsessed with Sandy Hook school shooter Adam Lanza and believed murdering her unnamed classmate would create a ‘blood bond’ with the shooter and help resurrect him.

She allegedly planned to stab the boy in the stomach or cut his throat with Lippert’s help, then leave flowers at the scene and smoke a cigarette.

Isabelle Valdez, 15, and Lois Lippert, 14, were charged with attempted murder after allegedly attempting to kill their classmate at Lake Brantley High School in Altamonte Springs, Florida

The teen best friends are being charged as adults. They were denied bail on Wednesday and will return to court next month

Valdez and Lippert, who attended Lake Brantley High School in Altamonte Springs, did not realize they were being recorded in the back of the police cruiser.

‘I’m not killing myself,’ Valdez said in the video. ‘Killing yourself is for retards. I’m not a stupid retard that gives up, please. I think I am retarded, though.’

She then turned to Lippert and laughed: ‘Why are you touching me with your butt?’

Lippert then told her best friend she already had a strategy for when law enforcement interrogated her.

‘If I have to be in a room where they have to record me or some shit, I’m going to pull out my t**s,’ Lippert told her.

She explained that doing so would make it ‘CP,’ meaning child pornography, prompting both teens to guffaw.

At another point in the video, Lippert said she wished she had ‘gotten my diagnoses before this.’

Valdez replied: ‘Dude, I thought I was going to get sent to the psych ward. That’s why I was so excited about everything. Think I would be so jolly if I was going to jail?’ 

Valdez, who is due back in court April 29, said in the cop cruiser footage that she thought she was ‘going to get sent to the psych ward’

Prosecutors claimed Lippert sketched sexually explicit and graphic drawings of the boy Valdez allegedly planned to murder 

The teens’ alleged murder plot was stopped when a fellow student ‘heard something from the pair’ and reported it to law enforcement, which prompted an investigation.

Their target’s name was redacted in legal filings viewed by the Daily Mail. 

Valdez and Lippert have been charged as adults with attempted murder. They were arraigned Tuesday where they pleaded not guilty.

Eighteenth Circuit Court Judge Melanie Chase denied the pair bail the following day, even as Lippert’s parents testified that their daughter would get counseling and therapy.

‘The video that I watched, she thought this was cute,’ Chase told the court.

She added: ‘I don’t want her on the internet talking to young folks about this.’

After being arrested, the teens talked about how they ‘were supposed to spread our story’ around the so-called ‘true crime community’ online.

Valdez allegedly planned the murder on Discord, with prosecutors pointing to texts between the teen girls as evidence of the supposed scheme.

‘Its [sic] gonna be over by tomorrow,’ Valdez messaged Lippert around January 22.

She also wrote: ‘Holy s** I’m gonna make a blood ritual for Adam Lanza LMAOOOO.’

Prosecutors pointed to texts between the two girls, in which Valdez told Lippert that she was going to ‘make a blood ritual’ for the dead Sandy Hook school shooter 

Prosecutors said Valdez planned the murder for about three months and was going to kill her classmate in a school restroom

Lanza killed 20 children and six adult staff members at Connecticut’s Sandy Hook Elementary School before turning the gun on himself in 2012.

Prosecutors claimed Valdez had been planning the killing for about three months and had become obsessed with the peer she allegedly targeted.

On the day of the planned attack, she allegedly met Lippert in a school restroom with a bag containing Clorox wipes, a towel to muffle the boy’s screams and the knife she intended to use.

‘The plan was to grab the young man, push him into a stall, stab him or slice his throat,’ assistant state attorney Domenick Leo told the court, per WESH. ‘It was a desire to create a blood bond to bring the fellow back to life.’

Valdez allegedly admitted she had ‘memorized all his classes,’ waited for the target to appear, secretly photographed him and took the pictures home to gawk at.

She told police investigators that the boy ‘reminded her of Lanza a lot.’

The teen girl also asked Lippert to sketch several renditions of the peer they planned to kill.

One of the drawings featured the boy dead on the floor with a rope tied around his neck next to Valdez.

Other drawings were sexually explicit and graphic, according to prosecutors.

Valdez and Lippert are due back in court April 29. 

The Daily Mail reached out to the Florida State Attorney’s Office for the 18th Judicial Circuit, which is prosecuting the case, as well as Edward Lopez, who represents Valdez, Bryce Fetter, who represents Lippert, and Lippert’s parents Ramona and Ross for comment.
