The mother found dead next to a bloody iron in a New York City hotel room was strangled and beaten to death, an autopsy has revealed.

A bloody iron was found near her body. However, there were no signs of forced entry, authorities said.

ABC 7 reported that a pair of bloody pants with a receipt in them were also recovered from the hotel room.

No arrests have been made and an investigation is ongoing. The woman’s son, 18-year-old Edwin Cevallos, spoke to his mother one day before her death.

But he said he saw changes in her demeanor a week before the tragedy. ‘She was so nervous and she was worried,’ Cevallos told the Daily News.

The teen said he was ‘in shock,’ adding: ‘Everything here in New York reminds me of her. Everything.’

Cevallos had been living with Oleas-Arancibia and her nephew in an apartment in Queens.

The Ecuador native came to the United States five years ago, leaving behind family including one of her other sons.

‘My mom, she worked very hard,’ said Cevallos, who joined her in the country two years ago.

While the teen conceded that he didn’t know his mother’s occupation, he said she was ‘always working for us to give us the best life in this country.’

The 18-year-old was waiting to meet her Thursday morning and phoned the police when he still didn’t see her at 1 pm.

Cevallos described his mother as ‘a very good person’ who was ‘always helping people’ and ‘never hurt anybody.’ 

‘She was always paying for everything. She never owed money to anybody. She was always looking to help them move forward,’ the teen said.

He explained that his mother had worked tirelessly to achieve the American Dream and provide a better life for her children.

‘She gave us the life that we always wanted,’ Cevallos said.

Cevallos admitted that he did not know what his mother did for work, but said she worked hard to give him the life he always wanted
