HIV scientist Jordan Willis whose Kansas City Chiefs friends died with ‘cocaine, THC and three times the lethal level of fentanyl’ is pictured in goggles in high school lab as it’s claimed classmates called him The Chemist for his drug cocktail concoctions

Kansas City Chiefs fan Jordan Willis was dubbed ‘The Chemist’ in high school for concocting drugs so friends could get high – and DailyMail.com can exclusively reveal a photo of him in the lab during his senior year.

A source claims that 38-year-old Willis – who says he was unaware that his three close friends died on his property last month after a football party – created the specific cocktails after asking classmates exactly how they wanted to feel .

“He always said to them, ‘How are you feeling today?'” the source told DailyMail.com. ‘I’ll make something up for you that contains this or that ingredient.'” He would tailor-make medications for them.

“Everyone in that circle called him The Chemist.”

Willis – who has reportedly entered rehab and is suffering from depression following the deaths of friends Clayton McGeeney, 36, Ricky Johnson, 38, and 37-year-old David Harrington – became an HIV researcher.

His lawyer has claimed: ‘He had absolutely nothing to do with their deaths.’

Families of the dead men have revealed that police told them the three dead men had high levels of illegal drugs, including three times the lethal level of fentanyl, as well as THC and cocaine in their systems. The final results of the toxicology tests have not yet been released.

The accusation comes as DailyMail.com can reveal a photo of then 17-year-old Willis wearing goggles in a laboratory at Park Hill High School in Kansas City, Missouri, with two fellow students.

A caption next to the 2003 high school yearbook photo reads, “With a keen eye, senior Jordan Willis (and two others) look at their lab papers before measuring out the chemicals needed to complete their lab on January 15th.

“AP chemistry was a class designed for students who plan to use their scientific knowledge for a possible career.”

Although it was initially believed that his three friends froze to death after the party as they watched their team narrowly beat the LA Chargers on January 7, the consensus among family and friends is that drugs could have been responsible.

Clayton McGeeney’s cousin Caleb claimed so News Nation that Willis had a long history of making drugs for friends.

“Jordan is the chemist,” he said. “Jordan is someone who has been known since high school for making medicine for people to make them feel better in certain situations.

“That’s how they all knew him.”

Apparently alluding to the night of the party, Caleb said, “It was easy for them to have fun…but he made a mistake.” Jordan was the chemist. He’s a scientist, right? He does what he has to do.

“To now use my cousin, my best friend, as a guinea pig? No.’

Willis left his home within 48 hours after police knocked on his door to question him on the night of January 9 about his three friends who lay dead in his backyard for two days.

Families who spoke to DailyMail.com said they could not rule out drugs as a possible cause of death for all three men.

Expert theories include that the men ingested enough fentanyl, combined with alcohol, to pass out after leaving the house and freezing to death.

Willis claimed he had not left his house in two days and was sleeping with noise-canceling headphones that blocked out the sound of the panicked knocking of his friends’ family.

He viewed the events of that night and the days that followed as a “huge, heartbreaking wake-up call,” a friend said.

“After the shocking loss of three of his close friends under extremely tragic circumstances, Jordan recognized that he had an addiction problem,” that friend said Fox news.

“He immediately checked himself into rehab after leaving his house and putting his belongings away.”

Willis is said to be devastated that he couldn’t say goodbye or attend his friends’ funerals – and is concerned about suspicions he caused their deaths.

“Not only is the entire country right now accusing him of killing his friends without any factual details, evidence or any charges, but he has also lost three close friends,” the same source previously said.

“He was unable to say goodbye or attend their funerals due to the circumstances of these wild speculations and accusations.

“No one seems willing to wait for the results of the toxicology report or other police facts from a case still under investigation to make these speculations.”

Willis claimed through his lawyer that he waved goodbye to the three friends at 2 a.m. after the end of the match, before sleeping on the couch and spending the next two days in the house, thinking nothing of the cars of his friends were still outside.

McGeeney’s desperate fiancée April Mahoney, 34, raised the alarm after breaking into the property just before 10pm on January 9 and finding £300 Harrington dead on the veranda.

She called the police and officers discovered April’s partner of 12 years and Johnson dead in the backyard.

Results from the autopsies and toxicology reports are not expected for at least three weeks, although it is not known if there are any preliminary findings.

Police still maintain the deaths are not murders, but have not ruled out a re-interview with Willis, who was led from the house in handcuffs after the discoveries.

Detectives are searching the victims’ phones to uncover potentially crucial clues from photos and pinpoint exactly who called each of them in their final hours.

A “fifth man” was at the party, but says he left at midnight when everyone was still alive and the guests were watching Jeopardy after the game.

DailyMail.com revealed he was another high school friend, Alex Weamer-Lee, 37, who has a criminal record that includes drug arrests, although the last was in 2012. No charges have been filed against him.

Flooring contractor Lee’s social media features many photos of him with Harrington, McGeeney and Johnson, including one of him in a living room with the latter two friends — all dressed in Chiefs regalia at another apparent watch party.

His criminal record includes three drug incidents in 2005, when he was 19 and living close to his former high school.

He pleaded guilty to two counts of unlawful use of drug paraphernalia and one count of possession of up to 35 grams of marijuana, records show.

Lee was given 20 hours of community service for one of the drug paraphernalia charges, but failed to complete it. He was subsequently sentenced to seven days in jail, according to a record amount.

Seven years later, while living in Aspen, Colorado, he was charged with a felony count of tampering with drug evidence after another man was arrested at a nightclub.

Lee was accused of taking two bags of ecstasy that were dropped on the floor of the venue when the accused dealer was seized by police.

He told officers he swallowed the contents of one bag and tried to hide the other, according to a report in the Aspen Daily News.

He ultimately pleaded guilty to the misdemeanor count as part of a plea deal and was placed on two years of unsupervised probation.

Judge Gail Nichols told him in Pitkin County District Court, “I think you learn a lesson the hard way.”
