Corrine Jackson shocked people with her antics in court.

Cape Town - A woman accused of killing her teenage girlfriend shocked the court on Monday when she laughed out loud during proceedings. 

Corrine Jackson, of New Woodlands, made weird hand signals and smiled and laughed with relatives in the gallery, leaving people gasping and giggling.

Jackson, 20, stepped into the dock at Mitchells Plain Magistrates’ Court dressed in black and sporting a pair of stylish spectacles.

She’s incarcerated at Pollsmoor Prison after her bail was denied last year.

She is accused of stabbing her girlfriend, Nadine Esterhuizen, 18, and attempting to cut her head off at a residence in Colorado Park on 27 September.

Blood splatter and footprints led cops to a locked toilet where they found the accused with two knives.

On Monday, State prosecutor, Farida Jacobs, told the court important evidence was still outstanding.

She asked that the matter be postponed to 25 April.

“DNA, exhibits and the cell phone records are still outstanding and we are waiting on crime scene photographs,” said Jacobs.

Prosecutors hope the cellphone records will shed light on the final hours of Nadine’s life, and what could possibly have led to her death.

Jackson appeared calm in the dock but shocked people with her antics as she was being led back down to the holding cells.

She stopped midway and began waving her hands in the air.

She made a circular motion and clapped her hands and then pointed nowhere specifically.

Then she smiled and laughed as she walked down the steps.

Nadine Esterhuizen, 18, was found lying in a pool of blood at her sister's home.

It was unclear what she was trying to say to family members in the public gallery.

During her bail application last year, Jackson admitted she suffered from a mood disorder which left her either happy or angry.

She was assessed by a district surgeon and declared medically fit to stand trial.

Jackson claims she acted in self-defence and only remembers stabbing Nadine once.

Nadine had opened a case of assault against Jackson in July 2017 after she was attacked at Strandfontein Pavilion and her cellphone thrown into the ocean.

Jackson also contravened a protection order which had been taken out in August by Nadine.

Nadine, from Portlands, was in matric at Athlone High School.
