Dwyer trial: Semen on mattress

Graham Dwyer’s semen and Elaine O’Hara’s blood were found on her damaged mattress.

The architect’s murder trial also heard yesterday that paint on a spade discovered near Ms O’Hara’s remains did not match paint found in Mr Dwyer’s garden shed.

Forensic scientists provided the evidence the day after Mr Dwyer’s wife, Gemma, said that she recognised the spade as one missing from their garden, referring in particular to “splatters of orangey red paint on it”.
