COLORADO SPRINGS, Colo. - We're learning more about the jailed 19-year-old man, accused of murdering two Colorado Springs teenagers.
Gustavo Marquez faces first-degree murder charges in the deaths of Derek Greer and Natalie Partida.
Now that the suspect is in custody, the question becomes: Who is he and what led to this?
On Marquez's Facebook page he's seen making gang signs and in one post called himself a Sureno. Sureno is a Mexican mafia from California that has spread to southern Colorado.
It's unclear if Marquez is an actual member or a wannabe.
"There are Surenos everywhere. You have Bloods and Crips that have never been related to any other Blood and Crips or Surenos that are only Sureno because that's what they decided to be," said Detective Jeremy Mathews, with the FBI of southern Colorado.
We spoke with two of Marquez's ex-girlfriends, who wish to remain anonymous.
One said, "He is not in a gang."
The other contradicted her, saying "He always talked about wanting to be in a gang."
You'll notice three dots tatted underneath Marquez's left eye, which translates to:
"My crazy life, la vida loca. They'll put the three dots on to represent that's how they live that they live the wild life," Mathews said.
Matthews says that doesn't mean Marqeuz is in a gang, but he often sees gang members with that same tattoo.
The other tattoo on his face reads "Santa Muerte." It translates to the saint of death.
"Santa muerte is the patron saint that a lot of the gang members have, especially those into narcotics," Mathews said.
Muerte is also a name Marquez goes by on Facebook.
Matthews says once someone gets involved as a Sureno, it's nearly impossible to get out.
"The best you can hope for is to get out alive but the consequences of this are death, prison, overdoses," Mathews said.
Marquez faces murder, aggravated robbery, kidnapping and child abuse charges in the deaths of two teenagers.
Marquez is scheduled to appear in court next Tuesday.
