Heartbroken girlfriend of Aussie surfer murdered in Mexico breaks her silence

San Diego local Emily Horwath shared photos and videos Sunday of her boyfriend Callum Robinson, 33, who was killed by carjackers alongside his brother Jake, 30, and their friend Jack Carter Rhoad, 30, and dumped on the bottom of a 50-foot-well in Baja California, Mexico.

"My heart is shattered into a million pieces. I don't have the words right now," Horwath wrote alongside an image of her and Robinson embracing, which she shared on Instagram.

A second photo she shared of the pair kissing was captioned, "You are one of one. I will love you forever."

Horwath shared more photos on Instagram, including one of Callum's brother Jake, who was also murdered.

"Always playing," she wrote alongside a picture of Callum hanging off a tree and then captioned, "I'd give anything for one more koala hug," alongside an image of the two in a loving embrace.

The heartbroken girlfriend also shared videos of Callum and herself dancing and goofing off at various events as well as an audio clip of a voicemail he left her, in which he tells her "Happy Tuesday! Good morning. It's 11:11, and I'm just thinking about you."

Howath wrote alongside the voicemail, "will be playing this on repeat."

"That's exactly who you were, positivity and smiles," she added.

Alongside the images, Howath also shared a GoFundMe for the two brothers that had raised nearly $160,000 by Monday morning.

The two Australian brothers and their friend, a California native, were last seen alive on April 27 during a trip to the city of Ensenada.

Their bodies were found last week and were positively identified by their families.

Chief state prosecutor Maria Elena Andrade Ramirez said during a press conference the alleged killers decided to target the surfers when they noticed their truck and tents.

"They approached, with the intention of stealing their vehicle and taking the tires and other parts to put them on the older-model pickup they were driving," said Andrade Ramirez.

"When they (the foreigners) came up and caught them, surely, they resisted," she added. "And these people, the assailants, took out a gun and first they killed the one who was putting up resistance against the vehicle theft, and then others came along and joined the fight to defend their property and their companion who had been attacked, and they killed them too."

Following the fatal confrontation, the suspects then burned the three men's tents before they dumped their bodies into a 50-feet deep well that was four miles from the murder scene, she said.

The thieves then covered the well with boards, the prosecutor said.

A fourth, badly decomposed body was also found when the bodies of the surfers were recovered. It is believed to be the remains of a rancher who owned the property and went missing two weeks earlier.  

Police have arrested Jesús Gerardo Garcia Cota, his partner Ari Gisel García Cota, and Jesus' brother Cristian Alejandro Garcia in connection to the three surfers' disappearance, but haven't charged them with murder.

At least one of the suspects, Jesús Gerardo Garcia Cota, was believed to have been directly responsible for the slayings.
