The investigation into Liam Payne‘s death may help convict a few individuals who are partially to blame for his death… but some of the details being revealed are such a punch in the gut.

The One Direction singer spent his final days partying in Buenos Aires, taking too many drugs until he was too high to fully comprehend what he was doing. Barely conscious, he went off the balcony of his hotel room and plummeted to his death. It’s unclear if he intended to drop or not — the latest reports suggest he was trying to sneak out and just fell. Local authorities say he was not even conscious when he hit the ground, so he may have literally blacked out mid-climb.

Terrible.

He wasn’t pushed. But that doesn’t mean no one should face any blame. One person has been charged with abandonment of a person followed by death, two others are charged with supply and facilitation of narcotics.

On Tuesday TMZ obtained court docs in which local prosecutors explain their decision to file the charge of abandonment against Liam’s friend Rogelio “Roger” Nores. Liam’s father told authorities that in May Nores had volunteered to take care of Liam — to make sure he stayed clean. Apparently the trick was keeping him busy and never alone. You’ll soon see why Roger was persona non grata at Liam’s funeral.

But did he fail despite his best efforts? Or was he not really trying? Prosecutors say Roger knew his “friend” was off the wagon, and they have proof. They’ve put together an hour-by-hour accounting of Liam’s final day, and it includes texts to Roger that make it clear what’s going on. First, at 10 p.m. the night before he ordered a dangerous amount of whiskey — 4 bottles. But that was just the beginning. At 6:36 a.m. he ordered 5 more bottles. Just a few minutes later, around 7 a.m. he texted Roger telling him about his partying. Specifically, and we’re sorry to those who will be upset to read this, he wrote: 

“Dude I think I’m going to f**k a hooker”

Oof. We knew he’d partied with girls the local police later identified as prostitutes. We don’t know how many fans held out hope he was just looking for companionship from the escorts and not sex… We know the prostitute reveal was a huge blow to his girlfriend Kate Cassidy, who had returned to their home in the US a couple days earlier. But yes, it does sound like he was cheating.

It gets worse for Roger than for Kate. Because Liam allegedly texted him just a couple hours later at 9:32 a.m.:

“Can you get 6 grams?”

This is the guy who’s supposed to be keeping Liam clean, and he’s texting him to supply him with cocaine? Or something worse??

Roger did show up to the hotel and have breakfast with Liam… who had whiskey for breakfast. Per the docs, a maid told investigators he got back up to his room and was desperately searching for his “powder.”

At 11:30 a.m. the two sex workers arrived. They said Liam asked them for cocaine. He was apparently out. He texted one of the hotel employees facing charges at around 2 p.m. for another hookup:

“I’m gonna need another 7 grams for today”

It was two hours later, about 4 p.m., that Liam was seen in the lobby, “visibly drunk.” You’ve probably seen the photos by now, in which the singer basically had to be carried back up to his room. It was after that he went out onto the balcony and fell. He died at 5:07 local time.

We wish we could say something else happened… but that’s what the investigation has turned up. So sad.
