MANILA, Philippines - A woman was killed and her body was burned inside a motel room allegedly by her boyfriend, police said Tuesday.

The 20-year-old victim, who hails from Cebu, was burned almost beyond recognition.

She was stabbed 3 times and her neck was slashed, investigators said.

The suspect, 44-year-old Raymond Camarse, was arrested while he was trying to escape from the crime scene.

He was nabbed because his car broke down outside the motel.

Police found a suitcase filled with clothes and a knife inside the suspect's car.

Camarse is believed to have poured either kerosene or gasoline on the woman's body after killing her.

Firefighters said they thought the case was a simple fire incident until they discovered the women's charred body on the bed.

Motel employees said Camarse and the woman checked in 8 a.m. on Tuesday.

They later noticed thick smoke coming from the couple's room and called for help from firefighters.

Senior Police Officer 2 Roger Baltazar said motel staff also became suspicious because Camarse suddenly checked out without the woman.

The suspect told police that he wanted to break up with the woman but the victim refused, Chief Inspector Roderick Tonga said.

Police are now trying to contact the victim's relatives. - Report from Jenny Reyes, ABS-CBN News
