A 65-year-old man is facing a murder charge in Corpus Christi. Police say he shot a woman early Monday. She died. The day before, he warned a neighbor it was coming.

Alberto Valdez got arrested after police got a 911 call. The call came in around 12:45 a.m. Monday. It came from a home on Christie Street, in the Midtown area. Police say Valdez and the woman knew each other.

The warning is what stands out most. He told a neighbor hours before it happened. What do neighbors see and not report, right before a tragedy hits? That question sits at the center of this case.

The 911 caller said Valdez had shot a woman. While cops drove over, another call came in. It said Valdez "lost it and got mad" right before he killed her.

When cops pulled up, Valdez was outside. He was waiting for them. They arrested him right there. He did not fight back.

Inside, cops found the woman in a hallway. She had gunshot wounds in her chest. She had one in her neck too. Cops tried to help her. She had no pulse. Paramedics got there. They said she was dead.

Cops searched the home. They found a gun in the kitchen. They picked up shell casings as proof. All of this went into what police call an arrest affidavit. That is a sworn paper where police write down why they made the arrest.

A neighbor later talked to police. He said he spoke with Valdez the day before the shooting. Valdez told him, "If you hear gunshots later, you already know it's me." The neighbor said Valdez had been mad at the woman for a while.

Police say Valdez later told detectives that he shot her.

Corpus Christi sits on the Gulf Coast. It is in Nueces County, up the coast from the Rio Grande Valley. Cases like this show how fast a fight between neighbors can turn deadly. A warning that sounds like a rant one day can turn real the next.

Domestic fights and neighbor disputes do not always look dangerous at first. Police say a warning like the one Valdez gave should never get brushed off. If someone tells you they plan to hurt another person, do not wait. You can call 911 right away. That one call could save a life.

Nueces County has seen its share of violence tied to fights that started small. Neighbors, roommates, and exes make up a big share of who knows a suspect before police ever do. That is why tips matter so much in cases like this one.

Cops booked Valdez into the Nueces County Jail. He faces a murder charge. That is a serious felony in Texas. It can mean 5 to 99 years in prison. It can even mean life in prison. Judges in Texas often set high bail in murder cases. Sometimes they set no bail at all. The charge is that serious.

Police have not said if Valdez faces more charges. The case stays open. It is not clear yet when he goes to court. El Tejano will keep following this story as it moves through the courts.
