A house which burned down in Porirua's Titahi Bay this morning is the same one in which two women were killed three weeks ago. The Morere Street house has been extensively damaged after it was set fire to just before 6.30 this morning.

It is the same place where 16 year old Jashana Robinson and 21 year old Joelene Edmonds were killed on June 26. Joseph Ogle, aged 28, has been charged with their murders and with breaching a protection order.

Police say the Housing New Zealand property was empty at the time of the blaze, which is being treated as suspicious.
