Russell Field, whose son Matthew was struck and killed alongside his pregnant fiancee by a teenager in a stolen car, has won the seat of Capalaba from Labor’s Don Brown.

Brown has conceded the seat, and Field currently has more than 43 per cent of the preliminary count.

Cracking down on crime has been one of the LNP’s main pillars in the Queensland state election campaign.

Speaking to Nine News, Field said he hoped he would be able to make change for “all victims, past, present and future”.

“We can’t let Matt, Kate and Miles’ death be in vain, and hopefully this is something where we can achieve something, some good for ourselves and others, to give us a little bit of legacy, or give Matt Kate and Miles some legacy.”
