The phone rang early in the morning, and Katie’s friend answered, expecting to hear her voice. Instead, a man whispered, “Katie. ”
Then there was just heavy breathing. And the line went dead.
Katie Lach had left for a first date the night before, just days before Christmas. She was a 23-year-old teacher from a London suburb, the youngest of three daughters, loved by her students and known for her energy. She coached water sports, volunteered at the Olympics, and helped kids from low-income families in America. Now her friend was calling her parents in a panic, telling them Katie had never come home.
Katie had told her parents she was spending the evening with a friend. Instead, she’d gone into London to meet a man named Carl, someone she’d been messaging for weeks. He’d said he was a lawyer, fresh from a stint in Moscow, with his own firm and a passion for humanitarian writing. They clicked quickly.
She wanted something serious, and he seemed perfect. Her friend told her parents everything. Katie had texted saying Carl was running late, then that the date was going really well. That was the last message anyone received.
Katie’s parents found Carl’s social media and wrote to him directly. He replied almost immediately, saying Katie had been with him until the early hours, but she’d left in a taxi and he didn’t know where she went. They weren’t satisfied. Katie’s father looked up Carl’s home address and went there himself.
Carl’s mother answered. She said her son hadn’t been home all night, that he’d only come back after noon and was out walking the dog. Katie’s father explained what was happening, and Carl’s mother called her son. That’s when Carl told her the truth.
He said he’d killed Katie. He said he was a monster, and he told her not to cry for him. He explained that he’d gotten extremely drunk, strangled Katie, wrapped her in a blanket, wheeled her onto hotel property in a luggage cart, and left her in the bushes. He’d planned to confess after Christmas, he said, because he didn’t want to ruin the holiday for his parents.
Then he told her where he was sitting: a bench in a park. Police found him there, calm, waiting. His clothes were stained with blood, and his skin was covered in scratches. He told them exactly where to look.
The medical examiner later confirmed Katie had been strangled. Her body was covered in defensive injuries, evidence she’d fought hard to survive. And there was more. Carl had sexually assaulted her after she was already dead.
In his first interview, Carl said almost nothing. He ignored the questions and sat in silence. But then his mother came forward with what he’d told her in that phone call. He claimed it was an accident.
He said Katie had agreed to something extreme, that she’d placed his hand on her throat herself, and he’d strangled her by mistake. No one believed him. Not the police, not the prosecutors, and eventually, not even his own defense. The timeline told a different story.
Katie had met Carl near a tube station, and they’d gone to a bar where he drank heavily. Around 1:30 a. m. , Katie ordered a taxi from her own phone, setting the destination for a hotel about 40 kilometers away.
The roads were packed with holiday traffic, so the ride took two hours. Katie paid £65 for the fare, and when Carl got sick in the car, she paid another £80 for the cleanup. At 3:30 in the morning, they arrived. Carl could barely stand, so Katie had to guide him to the room.
He’d booked that room under his own name before he even met her. Katie came back down to the front desk and asked for two toothbrushes. She also ordered two breakfasts for the morning. Around 9:00 a.
m. , Carl paid to extend the checkout time, and when housekeeping finally came in, all the bed sheets were gone and the window lock was damaged. Detectives started looking into Carl’s past. They quickly discovered he wasn’t a lawyer at all.
No law degree, no firm, no career. And his history was worse than they imagined. He’d been arrested in 2009 for assaulting his girlfriend. He’d spent years in and out of psychiatric care.
In early 2015, while living with another girlfriend, he told a hospital nurse he wanted to kill the girlfriend’s sister, strip her, and sexually assault her. When the nurse reported it, Carl threatened to kill her too. He’d called police himself once, saying he felt like killing someone, and that he was standing outside his girlfriend’s house. A psychiatrist evaluated him, and Carl admitted he was excited by thoughts of murder.
He said the urges had been there since his teenage years and were getting stronger. He pleaded guilty to threatening to kill his girlfriend’s sister, but instead of prison, he was released on bail. He ended up back in the hospital, transferred to a separate unit because he’d been having sexual contact with female patients who couldn’t consent. At one point, he looked at hospital staff and said, “When I get out of here, I’m going to kill someone.
Write that down. ”
That was in mid-September. Months before Katie died. But police didn’t treat it as a criminal threat.
The medical board decided he might have said it out of stress. Just days later, he was discharged and moved back in with his parents. On December 2nd, he received a nine-month suspended sentence for earlier threats. He was ordered to undergo a year of psychiatric treatment.
And in mid-December, less than two weeks before Katie was murdered, doctors concluded he wasn’t a danger to the public. The problem was that no one had the full picture. His records were scattered across different hospitals and different police departments. Important information never followed him.
While he was free, Carl was active on dating sites, talking to about 20 women at the time Katie was killed. The day after her murder, before his arrest, he called one woman he’d been messaging for two months and told her he’d killed someone and was going to prison for a long time. He’d been going on dates with others, using the same pattern: same meeting area, same bar, a hotel booked nearby. He never hurt any of them.
But he already had another date lined up for Christmas Eve. In March 2016, three months after the murder, Carl suddenly pleaded guilty. But he still refused to talk, and he refused to let police into his phone. For months, the case stalled because no one could access it.
Prosecutors were convinced that whatever Carl was hiding had to matter. And they were right. Eventually, Carl gave them the passcode. Inside the phone, they found disturbing photos of Katie’s body, taken after he’d assaulted her.
Only then did he offer an explanation, and it was the same accident story. He claimed Katie placed his hand on her throat. He claimed it was all consensual. But even in his own version, he admitted he assaulted her after she died.
He admitted he hid her body, then sat down, ate his breakfast, and checked out of the hotel. A well-known psychiatrist evaluated him before sentencing and concluded Carl posed a serious ongoing danger to women, and that treatment was unlikely to ever change that. Carl was sentenced to life in prison with a minimum of 26 years. His lawyer read a letter in which Carl apologized to Katie’s family, while Carl himself stayed silent.
But Katie’s parents didn’t only blame him. They blamed the system. England’s National Health Service, the police, the hospitals. They said if all the warnings about Carl had been properly shared, he might have been kept away from the public.
A formal review was launched. Independent experts agreed coordination between agencies needed work, but they concluded that even with perfect information, this specific murder might not have been predictable. The story didn’t end there. In 2017, Carl attacked a prison guard who refused to bring him cigarettes and tea, adding three more years to his sentence.
In 2021, six years after Katie’s death, Carl was found on the floor of his cell in a pool of blood. He was rushed to the hospital but died there. He’d been alone at the time. Katie’s parents still speak about what happened.
They say the bigger issue was never really fixed. No major concrete changes were made to how medical institutions share information. And they keep repeating the same words: if the system had connected the dots sooner, their daughter might still be alive.
