"I've done nothing but cry for the last four days," he said.
Segura is grieving his oldest daughter's death and trying to understand the reason behind it.
"He didn't want anybody else to have her," he said.
On Saturday, League City police were called to the home on Driftwood that 32-year-old Katrina Gonzales shared with her boyfriend, Felipe Fernandez. Gonzales was dead, beaten with a hammer. He, police say, was incoherent. Her family fears it's an act setting up his defense.
"That's not him. He always very coherent, he was always very social," Segura said.
Instead, her father believes Fernandez was mad she was moving out.
"She was leaving him and he didn't want her to and he probably just snapped," Segura said.
He says Fernandez was possessive and at times abusive. He wants him to pay.
"If he killed my daughter like I think he did, I hope he stays in jail for a very long time. I hope he suffers way more than she did," Segura said.
Gonzales was a mother devoted to her two girls. Caring for others, her father says, was her calling. She had even hoped to make it her profession.
"She really wanted to be a nurse, Segura said.
League City police have not released a motive. Fernandez remains in the Galveston County Jail charged with murder.
Meanwhile, the family has set up a fund for anyone wishing to help Gonzales' two daughters, who are aged 11 and 5.
