Hilda Cabrales, who was left unconscious outside a Los Angeles hospital two hours after her model friend Christy Giles' dead body was dumped outside a different hospital in the area, died the day before her 27th birthday. The 26-year-old passed away Sunday after doctors at Kaiser Permanente West Los Angeles declared her brain dead on Friday, Cabrales' father, Luis Cabrales Rivera, confirmed to The Sun. Rivera, along wither her mother, Marcela Arzola, decided to donate Cabrales' organs as a her 'last act of love'. 'My daughter would have been 27 today and we are very, very, very sad because it's a loss that we will never forget and nothing will ever be able to fill,' Rivera said. 'This was a very, very hard process for us, sixteen days of anguish, but I also believe that God gave us that time to prepare to accept what was going to happen.'

The next day, after not replying to text messages for nearly 12 hours, Giles' dead body was left on the sidewalk by men in balaclavas driving a black Prius with no plates at Southern California Hospital in Culver City at 5 pm on November 14. Surveillance footage recorded the men dumping Cabrales' unconscious body outside Kaiser Permanente hospital in West LA two hours later. Cabrales' parents immediately flew from Mexico to be by their daughters' side when they learned of the tragedy. 'Her mother Marcela, my younger daughter Fernanda, my wife Carolina, and I were with her, saying goodbye,' Rivera said, recalling his final moments with his daughter. 'At 6pm we went down with her to the operating room, and the medical staff paid homage to her for the great act of love she was doing by donating her organs.' The family paid their respects to Cabrales and honored her with a moment of silence, as well as the playing of her favorite song.

Her family decided to donate her organs as a her 'last act of love' 'My daughter would have been 27 today and we are very, very, very sad because it's a loss that we will never forget and nothing will ever be able to fill,' her father Luis Cabrales Rivera (pictured) said He also read his daughter a heartbreaking letter before the donation process began. It said: 'My daughter, my precious girl, I love you and always will. You have been and always will be my beautiful girl. 'Go to heaven without any worry. Even though your physical departure hurts us we know you are going to a better place. Don't worry about anything my queen, I will wait for the day in which I can hug you again. 'My love, thank you for all these years and for having taught me so much. I will look after your boy Tomas (Cabrales' dog) and your sister Fer. 'Caro and I will always have you in our heart and mind, rest in peace my daughter, my Hiyi (Cabrales' nickname).' Soon afterwards, Cabrales was taken into the operating room. 'We left at 7pm to get some rest but with the certainty that our girl is in the presence of God, resting and waiting for justice in her case,' he said. 'At around midnight we received a call from the organ transplant department to say that the process had ended and thank us again for making the decision to give life to others.' Doctors told Rivera they were going to donate at least nine of Cabrales' organs. 'In a year's time we may be able to meet with the people who received the organs,' he said. 'As a family, we would like to know where our girl is, although we of course respect people's privacy too.' They expect to receive her ashes in four to six weeks, at which time the family will take her to Monterrey - where she lived for the last ten years - so her friends can say goodbye. Then she will be taken to her final resting place in Durango.

She graduated cum laude as an architect from Monterrey University two years ago. She and Giles went out to the SoHo House in downtown LA and then a nearby warehouse party on the night they died. The two women left the party in downtown LA with men they allegedly met and ended up at an apartment building in West LA, the third friend who left early said. It had previously been reported that both Giles and and Cabrales were found with heroin in their system- a drug friends and family swear neither girl would have taken voluntarily. Rivera explained: 'Hilda told me that she would sometimes smoke marijuana to help her to get to sleep but the drugs that were found in her system were not drugs she would have taken herself.' 'Her mother is a doctor, her stepfather is a doctor and they have always told her that she should not take opioids because they could cause irreparable damage or cardiac arrest.' Giles' husband, Jan Cilliers, 41, assumes that the women were offered a ride to an after-party but never made it. He tracked Giles' phone at 1:30 am and shared her location as an apartment building at 8641 West Olympic Boulevard. He posted a photo of the address asking his social media followers: 'Anyone know someone that lives here?' Photographs and videos taken late the night before the women were left at the hospitals show Giles and Cabrales dancing and laughing at a warehouse party Giles and Cabrales went out for their friend described as a 'very normal' Friday night While both Giles (left) and Cabrales (right) were found with heroin in their systems, their family and friends insist the women never would have willingly taken the drug Detectives have since been spotted at the apartment building where they interviewed two of the three men Cabrales and Giles spent their final moments with. The men, who rent an apartment in West Hollywood that Giles' phone recorded as her last live location, allegedly admitted to cops that they took the girls home from the warehouse party, claimed the women took drugs and overdosed, and that they immediately took them to the ER. However, texts from Giles' phone reviewed by DailyMail.com cast doubt on the men's alleged account – leading her husband to believe they forcibly drugged both women. After arriving at their home, an apparently uncomfortable Giles texted Cabrales 'let's go' with a wide-eyed emoji at 5:30am on Saturday morning. Cabrales replied 'Yes. I'll call an Uber. 10 minutes away.' Texts between the two women showed Giles sent a message to Cabrales at 5:30am when they were at the apartment, reading: 'let's go.' Cabrales replied: 'Yes. I'll call an Uber' and then '10 minutes away'- however, the two were never picked up Four minutes later at 5:36am, a friend called Eddie who was at the official afterparty the girls had planned to go to texted Giles: 'Where you at?' - but that message was never read At 5:36am a friend called Eddie who was at the official afterparty the girls had planned to go to texted Giles: 'Where you at?' Read receipts show Giles never read the text, nor any others after that, and Uber records show the women never got in their cab. Cilliers believes that in those six minutes, something happened to his wife and her friend that left them incapacitated. But it wasn't until 12 hours later, at 5pm on Saturday, that CCTV at Southern California Hospital in Culver City showed men in masks and hats pulling up in a black Toyota Prius with no license plate and dumping Giles' body – and another two hours before Cabrales was left at nearby Kaiser Permanente hospital in West LA. Cilliers said hospital staff told him both women's bodies were cold when they were admitted, which could mean that whatever killed his wife had happened several hours earlier. He said though his wife led a glamorous life, being signed to Wilhelmina Models age 14 and traveling the world for photoshoots, she 'kicks a** and is very street smart.' Giles' (left) husband Jan Cillers (right) says he knows the name of the men who were last seen with the two women. Cillers (pictured) and Cabrales' father, Luis Cabrales Rivera, have confirmed that many women have made complaints to them and police about the suspects Giles' husband also claims to know the men who his wife and Cabrales were last seen with. He and Giles' best friend, Sandy Evangelista Robinson, have reportedly been receiving messages from other women sharing other similar bad nights with the men. When he shared the names of the men on social media, one of their ex-girlfriends allegedly shared her story writing: 'He's a dangerous person, and I've been contacted by numerous women who've also experienced abuse from him.' Rivera also confirmed suspicions that have circulated social media: 'the people behind this have done it before.' Although the suspects' names have not officially been released complaints about several suspects have been coming into Giles' husband, friends, and the Los Angeles Police Department. 'We want people to continue to be aware of this case until those who are responsible for what happened to Hilda and Christy are behind bars,' Rivera said. 'The detectives have spoken with us several times and they told us that for the LAPD this is personal because the people behind this have done it before but it had never gone as far as this,' he confirmed. The investigation into Giles and Cabrales' deaths remains ongoing. In fact, Rivera said the Federal Bureau of Investigation may get involved in the case. 'I have heard that the LAPD may involve the FBI in the case in order to get those responsible behind bars,' he told The Sun. 'If they need support from federal agencies to speed up the process they should get it, that way we can close this chapter.'
