Beverly Maire remains in disbelief. Her fiance of four years Curtis Shelley was gunned down in front of her Sunday afternoon.

The shooting happened in the 1000 block of Cedar Drive. Maire said the pair were walking home when Shelley and one of his neighbors got into an argument involving a family dog. The family claims the suspect previously stabbed the family dog.

Things escalated during the argument about the stabbing and Maire said the suspect shot Shelley in the chest with a sawed off shot gun.

"The guy just killed my fiance', he took the love of my life away. I grabbed his hand and begged him not to leave me, his eyes were rolling back in his head and he stopped just for a second and just looked at me and then he stopped breathing," said Maire.

Maire said what the suspect did next shook her to the core.

"He looked at me and said you better hope they can save him," said Maire.

Shelley was taken to the hospital in critical condition where he later died.

Shelley's cousin-in-law, Stephanie Jones, expressed her anger to Channel 6 on Monday. She said her calls to police about the incident went unanswered and the entire situation was traumatic.

"Back in the old days, people fought and now they pull guns," Jones said. "It didn't have to go that way. There's no reason to gun somebody down in the middle of the street. Sometimes it seems like when you're getting your life together, that's when God takes you. And Curtis was getting his life together."

The family said they want the suspect to spend the rest of his life behind bars for what he did, and added they are considering moving out of Killeen.

Officers took the suspect into custody after the incident. Police told Channel 6 the case will be sent to the District Attorney's office for review. The family has started a GoFundMe page to raise money for funeral costs. The details can be seen here.
