Dozens of Jesus Trejo's friends prayed Thursday night outside his home in Homestead where they also offered condolences to his family.
"I didn't expect this many people to show up," said Trejo's sister, Jazmin Trejo. "I see that my brother was really cared for and that I really appreciate."
The friends also lit candles in memory of the teen, just hours after police found his body in a canal near the Everglades, off Ingraham Highway and Southwest 232nd Avenue.
"Who throws someone out there like that to die in the middle of nowhere?" asked Jazmin Trejo.
The news that no one wanted to hear started trending on Twitter among Trejo's friends and even from strangers.
AdrianaAlonzo99 tweeted, "R.I.P. Jesus Trejo ((and everyone else we have lost.)) It's hard dealing with the pain ((but stay positive and know that they are in paradise."
Princess Jeny tweeted, "Enjoy life you never know when will be ya last day."
Tuesday was the last day friends said they saw Trejo alive.
"He was always happy," one person said.
While none of the friends gathered on the darkest of nights wanted to speak to Local 10 on camera, they continued praying for answers.
Some told Local 10's Baron James that Trejo had gone to a popular hangout in the area where his Honda was also found.
Jazmin Trejo thinks someone murdered her brother, before dumping his body in the water 16 miles away from his home and his loved ones.
"All I know is that he went to go meet someone there, that he's never met before, that's all we know," said Jazmin Trejo.
