A SADISTIC survivalist who killed an entire family after breaking into their home has been found dead after a four-month manhunt.

Disturbing TikTok clips of the mass killer surfaced in the weeks after the incident, featuring him laughing maniacally at the camera while sporting a sinister clown mask.

Alexander Meisner, a 61-year-old Kazakh national, massacred an entire German family including a teenager and his parents.

Meisner, himself a dad-of-five and grandfather, entered the Schulze family home in the Rhineland village of Weitefeld in the early hours of April 6.

He carried out the evil assault in the dead of night armed with a knife and a gun.

Nadine Schulze, a 44-year-old worker at a local butcher shop, managed to call the police and shout for assistance over the phone as Meisner entered the premises.

Moments later, she was stabbed and shot dead by Meisner.

Police quickly responded to the haunting call and rushed round to the house.

They found Nadine’s lifeless body alongside her 47-year-old husband Kai and Kilian, the couple’s 16-year-old son.

All three had suffered fatal injuries from gunshot and stab wounds.

Some of the family were reportedly found bound with cable ties.

Meisner, now nicknamed the “Westerwald Killer” had already managed to escape the scene.

He is believed to have fled through a window and quickly became the focus of an international manhunt when he was named as the lead suspect.

Police had issued an arrest warrant along with a reward of up to €10,000 leading to his capture.

Interpol also confirmed that a Red Notice had been issued for his arrest after a request by German authorities.

Then on April 26, nearly three weeks after the murders, several horrifying videos were shared of Meisner online.

One showed the man maniacally laughing as he stared into the camera all as he wore a clown mask.

Another posted the same day showed him stripped down to his underwear and pouring freezing buckets of ice water over his head.

Officials are still unsure if Meisner was behind the clips being posted onto TikTok or if they were posted on his behalf.

This is due to his body being found less than 2,000ft away from the Schulze’s home on August 5.

Cops said the badly decomposed corpse was partially hidden in a underwater in a swampy farmland between Weitefeld and Neunkhausen in Altenkirchen.

A firearm was also found next to his remains.

Detectives said due to the body’s condition it is nearly impossible to determine an exact cause of death or when Meisner actually died.

They are still investigating if he took his own life, died from his injuries during the killing spree or faced another grim demise.

Meisner was a known criminal to police as he had previously spent time in jail for headbutting and stabbing his ex-wife.

He was sentenced to four years and nine months in prison in 2011 after attempting to murder his ex-wife, Theresa.

Meisner is said to have only stopped the attack after one of his sons stopped him from finding another knife.

Neighbours had also warned of the behaviour from Meisner in the years before the family massacre.

Melanie Hoechtlen said she reported him for harassment in October 2023.

She told Bild: “He ambushed my dog and me on the path. Then he came close and asked if he could lick me.

“I reported him back then. He said he had been a lone fighter in his homeland of Kazakhstan and knew how to survive in the forest for weeks.”

Police have announced they have ended their investigations into the murders now that Meisner’s body has been found.

Mario Mannweiler, a senior public prosecutor, remarked: “The fact that the suspected perpetrator’s location remained a mystery for months has been a source of concern for us.

“While the idea that the suspect was no longer alive seemed plausible for several reasons, the lack of a body required us to explore other possibilities. Nonetheless, I’m relieved that this situation has now reached a conclusion.”
