POLICE are hunting an online dating brute who attacked a nurse, inflicting horrific injuries similar to a car crash victims.

Shey Webber, 34, may have lain injured in her Warranwood home for days before a courier noticed blood and signs of a disturbance.

Her profile on the online matchmaker website RSVP is at the centre of inquiries, police sources confirm.

Ms Webber last accessed the site on October 28.

Emergency services found the battered woman lying face down in the hallway of her Regency Terrace home at 10.20am on November 6.

Detective Senior Sergeant Graham Guy said she had been viciously assaulted.

''Shey has sustained significant injuries, which might be life-changing. I suppose one could say were consistent with that of a car accident,'' Sen-Sgt Guy said.

''It’s very, very vicious.''

Sen-Sgt Guy urged anyone who may have contacted Ms Webber via a dating site to call police immediately.

''We will find your details within her dating websites and eventually we’ll catch up with you,'' he said.

Ms Webber is in an induced coma in the Royal Melbourne Hospital in a critical condition.

Sister Tamika, a paramedic, asked for help to catch the ''heartless monster''.

A burglary gone wrong has not been ruled out, but detectives believe it more likely that she was attacked by someone she met online.

It appears nothing has been stolen, and there were no signs of forced entry.

Detectives are also investigating links to the classifieds website Gumtree, where Ms Webber was advertising for a tenant and had included photographs of herself.

The savage assault has devastated Ms Webber’s parents, Ainsley and Ashley Webber.

''We’re absolutely traumatised. It’s just unbelievable,'' Mrs Webber said.

Sister Tamika, in an online post, urged people to ''get justice for my gorgeous sis''.

Ms Webber was last seen on the Saturday before Cup Day, sunbathing in her backyard, and at shops a day earlier in her distinctive red convertible Toyota MR2 Spider.

''From Sunday on it becomes a bit of a blur as to where Shey was or what she did,'' Det Sen-Sgt Guy said.

The courier who found Ms Webber told police he had tried to deliver a parcel two days earlier, and was adamant nothing was suspicious then.

''(That) hopefully narrows down our field of time,'' Det. Sen-Sgt Guy said.

It is believed Ms Webber had lived at the house alone for about four years.

A neighbour said she had one or two boyfriends, who were ''nice guys'', and ''she kept to herself''.
