Man shot and killed younger brother during argument in Willis, Montgomery County deputies say

MONTGOMERY COUNTY, Texas (KTRK) -- Deputies arrested a man accused of fatally shooting his brother Thursday morning at a home in the Willis area.

Montgomery County sheriff's deputies said it all started as an altercation between a woman and a man.

Deputies were called to the 700 block of Pine Circle Drive for a shooting call around 3 a.m.

Investigators said 33-year-old Oscar Martinez and a woman were arguing at the home, and it got pretty heated. It's unclear what kind of relationship they had.

At some point during the argument, the woman called Oscar's 30-year-old brother, Julio Martinez, for help to try and deescalate the situation.

When Julio showed up, deputies said the two brothers got into an altercation. That's when Oscar allegedly shot Julio outside of the house.

The woman called 911 and investigators said Oscar left in his truck. Deputies found him in the neighborhood and arrested him. He's charged with murder. Investigators said Oscar appeared to be intoxicated at the time.

Deputies attempted to perform life-saving measures when they arrived, but Julio was pronounced dead at the scene.

"It was overwhelming when I heard it was two brothers. We really thought it was somebody in the house died. This is really shocking for the neighborhood because this doesn't happen here," neighbor Katina Spiller-Opperhammer said.

"You never see police cars?," ABC13 reporter Courtney Fischer asked. "No. When stuff happens, it's minor stuff. It's so sad because, I mean, my God, people don't realize how precious life is," Spiller-Opperhammer said.

Investigators said the woman was not injured.

ABC13 crews saw several children being led away from the houses behind the yellow tape at the scene. When asked if there were any children home when the shooting happened, or any other family members, investigators said they weren't sure.

The sheriff's office told ABC13 that deputies have been called to the house before for domestic issues.
