A Westminster man who allegedly shot his brother Thursday said he was concerned for his mother's safety during an argument between his brother and mother, according to court documents.

Reno Louis Valianti, 38, is facing charges of first- and second-degree assault, reckless endangerment, use of a handgun in the commission of a felony, and attempted first- and second-degree murder after allegedly shooting his brother in the stomach.

The Sheriff's Office and Maryland State Police responded to a reported domestic-related shooting on Sullivan Road in Westminster about 11:30 a.m. Dec. 12 and found a man outside who had been shot in the abdomen.

Police said the victim, 33-year-old Michael Valianti, was alert and conscious, but he was flown to the University of Maryland Shock Trauma Center where he underwent emergency surgery.

He was discharged from the hospital Sunday, hospital spokeswoman Cindy Rivers said Tuesday.

According to court documents, Reno Valianti told police he was in his basement bedroom when he heard his brother and mother, Rebecca Valiant, arguing upstairs.

After the argument seemed to end, Valianti told police he heard loud, banging sounds from the first floor.

Valianti grabbed his .45-caliber semi-automatic pistol and went upstairs because he was concerned for his mother's safety and believed he would not be able to defend himself against his brother due to a disability affecting his muscles, according to court documents.

Reno told police he saw his brother in the home's garage hit the side of his mother's running vehicle and demanded that he stop.

He told police that Michael then came toward him in a quick "charging" manner, which is when he allegedly shot his brother.

Steven Stahley, who lives at the house with the Valiants, told police that the brothers routinely argue and have for years. He described their relationship as "oil and water," according to court documents.

Stahley was not home at the time of the shooting.

While Stahley told police he owns a gun safe in the basement of the home, the gun used in Thursday's shooting is allegedly owned by Reno Valianti.

A preliminary hearing for Reno Valianti has been scheduled for Jan. 2.
