An inquest into three deaths in a two-car crash in East Sussex has found that two people were unlawfully killed.

The coroner at the Hastings hearing said the death of a third person, Kenneth Thornett, was by misadventure.
Perry Carter, 31, of Tonbridge, Kent, Mr Thornett, 48, and Aaron Hogg, 13, both of St Leonards, died in September 2004 on the Queensway, St Leonards.
They were killed when a Citroen Zx was in collision with a Ford Granada at a notorious accident blackspot.
Four other people suffered serious injuries in the accident.
Following the tragedy, Aaron's family launched a campaign to introduce speed restrictions on the 60mph road.
A petition with more than 1,000 names was gathered.
A speed reactive sign, red reflectors, road markings and reflective posts were installed on the road in January.
