A suspect in the case, Mark Hennessy, was shot dead by gardaí on Sunday evening at Cherrywood in south Dublin.
Hennessy, who was believed to be armed with a knife, was from Wicklow and married with children.
Jastine was reported missing by her parents following a report of a woman being forced into a car near Enniskerry on Saturday evening.
According to gardaí, the report of her disappearance followed an earlier incident near Enniskerry on Saturday evening.
Shortly after 6.15pm, gardaí received a report of a female pedestrian being forced into a car on the R760 south of the village.
Jastine's mobile phone was later found at the side of the road.

A garda helicopter, cars, support units, and ambulances were at the scene of the shooting at the business park.
As per protocol, GSOC has been notified of the incident and a team has been sent to the scene.
The search is continuing for Jastine.
