A 60-year-old grandmother found dead in her semirural Bullsbrook home is suspected to have been murdered by a former partner.
Major crime squad and Esperance detectives were last night questioning a 54-year-old man after local officers arrested him outside an Esperance grocery store about 7.45am yesterday.
Neighbours found Roma Pollitt dead on the kitchen floor of her Hillside Place home about 6.40pm on Wednesday after going to check on her.
It is understood police suspect she may have been killed in the early hours that morning.
A neighbour told police he heard yelling from the rental property on Tuesday night, with Ms Pollitt reportedly telling someone to go away.
The neighbour went to visit her the following evening and, through a window, saw her lying facedown and motionless.
The man called another neighbour for help and they went inside after finding a door slightly ajar.
Lights and the television were on and a tap had been turned on.
St John Ambulance officers were called but Ms Pollitt was dead.
Shocked friends said they could not believe that police thought she was killed.
She had survived a life-threatening brain infection last year that required extensive hospital treatment and rehabilitation.
Ms Pollitt, who lived alone at the property, has a son and daughter and four grandchildren.
Forensic officers scoured the home for evidence yesterday while detectives spoke to neighbours.
It is understood Ms Pollitt was no longer in a relationship with the 54-year-old but was still in contact with him.
The man being questioned had been living at a nearby Bullsbrook bus yard, where he prepared old buses for sale.
Detectives yesterday started examining the old bus he had been living in and talked to other workers at the property.
Witnesses said that Esperance detectives and uniformed officers arrested the man moments after he walked out of the IGA store in the southern coastal port town.
It is believed he had previously lived in Esperance and still has relatives in the town.
Major crime squad detectives flew to Esperance yesterday morning to interview the man with local detectives.Anyone with information about Ms Pollitt's death is asked to call Crime Stoppers on 1800 333 000.
