MIDLAND, Tx. (KOSA) -- A Midland mother is dead, and according to police, the man who stabbed her to death is on the run.
"I didn't want to believe it, but after seeing multiple police officers here - I had to come to a realization," Heriberto Santos said.
Santos rushed to the Midland Stripes on 4400 Briarwood Avenue Sunday morning to find his mother, the gas station's general manager Patricia Ruedas, brutally murdered.
Santos talked first to a police officer, "he said I'm sorry for your loss, but we are looking for the suspect. Do you know he is?"
Santos knew instantly it was his father.
Investigators said Santos' father Juan Ruedas attacked his estranged wife Patricia Ruedas with a knife around 6:45 a.m.
She died there inside the convenience store. Juan is still on the loose wanted for murder.
Santos said his father recently moved out, and his mother moved into a new apartment out of fear.
"We should have seen the signs," he explained.
Santos said his mother had a huge heart, and recently starting caring for three of her grandchildren.
"She was my rock. She helped me so much. She was strong, and we got through everything together," he said fighting back tears. "Now that she's gone, I have to look out for my little brother. I have to be his rock."
Ruedas is described as a Hispanic male, 5'6" and 140 lbs.
He was last seen wearing a black leather jacket and dark jeans.
If you know where 49-year-old Juan Ruedas is, you're asked to call the Midland Police Department or Midland Crime Stoppers at 432-694-TIPS.
