A love triangle leaves three people dead, including the suspect. This is the first time in at least 10 years that there's been a double murder in San Marcos.
The investigation has switched from a search for the suspect to the search for a motive. Police are waiting for autopsy results on all three deceased and they hope to have a clearer picture of what happened over the next few days.
"We have three young people in their 20's who are now dead, three families who are destroyed and three promising lives snuffed out," said Police Chief Howard Williams, San Marcos Police Department.
It was a love triangle turned deadly.
"Early in the morning he had called his roommate, told him he had hurt his girlfriend. He didn't say he killed her but said he hurt her and that he was going to go drive his car off a cliff," said Police Chief Howard Williams, San Marcos Police Department.
San Marcos Police, along with help from several other agencies tracked the phone of suspected shooter Daniel Brewster Stillwell. That led them to his body found inside his vehicle in Comal County, in an area commonly known as the Devils Backbone.
"We're not sure right now whether the collision he was in killed him. The vehicle was mangled pretty badly and it was a pretty serious rollover collision. Or whether he shot himself," said Police Chief Howard Williams, San Marcos Police Department.
Police had issued a capital murder arrest warrant for Stillwell after discovering the bodies of 22-year-old Hailey Nicholls and 26-year-old Jesse Robledo shot to death.
"I heard her screaming a lot and then I heard some more gunshots," said Cecilia Rodriguez, neighbor.
It happened inside of an apartment at Executive Townhomes early Thursday morning.
Nicholls and Stillwell were both students at Texas State University. Nicholls was currently enrolled as a fashion merchandising major; the last time Stillwell was enrolled was last Spring. That's where police believe they both met and began dating but after recently breaking up, Robledo stepped into the picture.
Police believe the weapon used in the crime is what Stillwell may have also used to take his own life.
"I wish he hadn't killed himself, I wish we could have taken him alive but we're pretty confident that he killed himself long ago this morning. We just hadn't found him yet," said Police Chief Howard Williams, San Marcos Police Department.
The two victims and the suspect were employees at the Chipotle Mexican Grill in San Marcos.
Current employees are being offered grief counseling.
Chipotle's corporate office sent us a statement saying:
"There are no words to express the shock and sadness everyone at Chipotle feels as a result of this senseless loss of human life. Jesse Robledo and Hailey Nicholls were devoted and admired members of our team, and our hearts go out to their family and friends. We are working closely with law enforcement investigators and will continue to do so."
