SABINA Nessa's heartbroken sister sobbed "it's not getting easier" after a "predatory" monster today admitted murdering her.
The primary school teacher, 28, was ambushed in a "premeditated and predatory" stranger attack as she walked to a pub in Kidbrooke, South East London, to meet an old pal.
Koci Selamaj lay in wait for a victim after driving from his home in Eastbourne, East Sussex, to London to attack a woman using "extreme violence".
Chilling CCTV footage captured the monster checking no one was watching before he started to run after terrified Sabina on September 17.
The monster pounced on her and battered her 34 times with a 2ft metal weapon – believed to be a red road sign – so savagely it broke into pieces.
He was then filmed carrying her away unconscious into the darkness.
The Albanian national is believed to have strangled her in undergrowth in what is suspected to have been a sexually motivated attack.
Sabina's body was found by a dog walker covered in leaves near the OpenSpace community centre the following day just 200 yards from her home.

Selamaj, 36, today pleaded guilty to murdering Sabina when he appeared at the Old Bailey.
Speaking outside court today, Sabina's sister Jebina Islam broke down in tears as told how the guilty plea was "difficult to digest".
She said it was a "step in the right direction" but did not bring her sister back.
Jebina added: "We as a family are broken and there is not a day that goes by that we do not think of her.
"There are no words to describe the pain we are going through and the pain which he has caused.
"The fact we will never know the motive for why he killed our sister is not only frustrating but heartbreaking.
"No family should go through what we are going through, and each day is not getting any easier."
MURDEROUS PLOT
Selamaj was arrested in Eastbourne at a ground-floor flat behind a row of shops and takeaways days after the brutal killing.
It came after police appealed for information about a suspect caught on CCTV at a nearby apartment block holding a red item.
The court was told Selamaj hatched his murderous plan three days before killing Sabina and booked himself into a room at the five-star Grand Hotel in Eastbourne.
He was seen on camera walking through the lobby wearing the same clothes as the suspect later caught on CCTV in Kidbrooke.
ANPR cameras tracked his Nissan Micra and mobile phone evidence helped identify his movements to London.
Selamaj, who was married at the time of the murder, also used his bank card at Sainsbury's in Kidbrooke to buy a rolling pin.
CHILLING CCTV
Haunting CCTV showed him lurking in the bushes at Cator Park for 30 minutes before unwitting Sabina arrived.
Alison Morgan QC, prosecuting, said: "The defendant is seen in effect loitering in locations around the park before spotting the deceased, checking to see if anyone else was nearby before turning and running after her.
"He is then seen to move towards the deceased and striking her repeatedly using a weapon which was approximately 2ft in length.
"In fact it was a weapon which appeared to break up during the course of the many strikes on the deceased.
"The CCTV footage shows the defendant then carrying the deceased, who appeared to be unconscious by that point, up a bank and effectively out of sight."
Around ten minutes later, Selamaj re-appears alone and picks up pieces of the shattered weapon lying on the ground before wiping a nearby bench down with wet wipes.
He arrived back at the £170-a-night Grand Hotel just after midnight and checked out the following morning.
After his arrest, Selamaj made no comment to officers except to deny murder when asked directly if he was responsible for killing Ms Nessa.
He later accepted being the person caught on CCTV and that he had hit Sabina a number of times.
TRAGIC END
Tributes poured in for the "amazing" primary school teacher after her shocking death.
Hundreds of mourners also gathered for a candlelight vigil to remember Sabina.
The Duchess of Cambridge – who left flowers at the vigil for Sarah Everard – said her thoughts were with Sabina's family and friends.
She tweeted that she was “saddened by the loss of another innocent young woman on our streets”.
Sabina's death also sparked outrage after she joined a growing list of women killed in public spaces in London in recent months.
Campaigners are demanding action to tackle violence against women in the wake of the tragedies.
Helen Ellwood, from the Crown Prosecution Service, said: "Sabina Nessa was 28 years old when her life was cut short as a result of truly evil violence inflicted on her as she walked through a park.
"Koci Selamaj has shown little remorse for his premeditated and predatory attack on a lone woman who was a stranger to him.
"His cowardly actions have devastated a family and caused immeasurable pain to all those who knew and loved Sabina.
"The prosecution was able to build the strongest possible case resulting in Selamaj admitting his guilt as a result of meticulous investigation led by the Metropolitan Police, which included an extensive review of CCTV footage and detailed forensic work."
Selamaj was remanded in custody to be sentenced on April 7.
