SAN ANTONIO – Monday marked nine years since a 20-year-old — with dreams of joining the Marines — was murdered outside his home in Northwest San Antonio.

FOX SA has covered Isaac Orozco’s case from the beginning. Over the years, the San Antonio Police Department has released surveillance footage and named persons of interest — bringing moments of hope — but the case remains unsolved.

Anchor Ashley Paredez met up with Isaac’s mother as she reflects on nearly a decade of grief, hoping this will be the year someone finally speaks up.

Since that day in 2016, Janie Edwards, has spent every July 28 — and most days in between — at the cemetery.

“My son was, he was young. He was only 20 years old,” said Janie Edwards, Isaac’s mother.

Isaac Orozco was shot and killed in front of their apartment near Culebra and Loop 410. His mother says a friend had picked him up for dinner. Two hours later, he was dropped back off.

“There’s a video. You can’t make out the person’s face, but there’s a video,” said Edwards.

Surveillance video from that night shows the alleged shooter pulling up.

“Toyota 4Runner, that’s what it looks like,” said Edwards.

Isaac can be seen at the bottom right in the video, looking the other way. Just moments later, shots were fired.

“I think he was scared and didn’t want to knock on the front door. He knew if he went around the sliding door… maybe he thought someone was going to chase him, follow him,” said Edwards.

Edwards says she ran outside after hearing the commotion.

“I was touching his arm. I was telling him not to close his eyes, but he was already cold,” said Edwards.

He had been shot once in his lower stomach, hitting an artery — and passed away in his mother’s arms.

“I was just in shock; I didn’t know what to do. I think I just froze at that moment, and I think from that moment on, God just took me,” said Edwards.

Isaac’s mother has held on to the light through the darkness — becoming the true force behind the fight for justice — with Isaac’s grandmother by her side.

“I’m always going to love him, till the day I get to see him again, you know. And I just want people out there to know that I’m not going anywhere,” said Edwards.

At one point, there were two persons of interest in the case.

“The owner of the car — that’s one. And then another guy that’s friends with the owner of the car,” said Edwards.

She tells us that early on, police confiscated what they believed could be the same black car from the video.

“They found gun residue in the window where the person shot but the person that the vehicle belongs to, he right away came up with an alibi — that he was shooting deer from a window,” said Edwards.

The original detective on the case retired around three years ago. Edwards still holds on to what he told her before he left.

“It’s going to crack any time now, and you need to stay close to that phone. So, I’m over here thinking there’s two people of interest and then from that to cold case, it just doesn’t add up to me,” said Edwards.

A new detective is now assigned to the case. Janie says although she continues sharing information, things are at a standstill.

“He was having an argument with somebody on Twitter but now, when it comes to me asking the detective, that person was never interviewed. It’s just — a lot of holes were in this case,” said Edwards.

Janie believes everything is likely connected, as the two persons of interest and the person from Twitter all went to the same high school. In the meantime, she continues to hold on to her faith.

“Our Lady of Guadalupe — we have a lot of faith in her, because she was a mom too and she knows my pain,” said Edwards.

She hopes whoever did this will also know her pain — and finally come forward.

Crime Stoppers is offering a reward of up to $5,000 for information leading to an arrest.
