The younger brother of triple homicide suspect David McNabb appeared in court Friday for allegedly violating a restraining order, but has not been charged in an assault that allegedly occurred just before the Dec. 28 slayings in Orcutt.
Brian McNabb, 40, of Santa Maria, was arrested Sunday and booked into County Jail on suspicion of battery with serious bodily injury for allegedly assaulting a family member in his Santa Maria home, according to the Santa Barbara County Sheriff's Office.
The assault reportedly occurred sometime before his sister, Nicole McNabb, 34, mother, Melanie McNabb, 63, and her boyfriend, Carlos Echavarria, 64, were killed in their Orcutt home on Dec. 28.
The Santa Barbara County District Attorney's Office has yet to file formal assault charges against Brian McNabb.
The defendant's older brother, David McNabb, 43, was fatally shot by sheriff's deputies after he barricaded himself, armed with a rifle, inside the Oakhill Estates home where the slayings took place.
Sheriff's officials believe the victims were brutally beaten and stabbed.
David McNabb and the three victims reportedly lived together inside the Orcutt home, along with Nicole McNabb's friend, who reportedly called 911 after returning home to the bloody crime scene.
On Friday, Brian McNabb made a brief appearance at Santa Maria Superior Court to be arraigned on a misdemeanor count of violating a restraining order, which had been filed against him by a family member who did not live at the Oakhill Estates home. The misdemeanor charge is unrelated to the assault, or any of the slayings, according to the District Attorney's Office.
The complaint alleges that the violation occurred on or between Dec. 29 and Dec. 31, immediately after the killings.
Brian McNabb pleaded not guilty, and will return to court Jan. 8.
His request to be released on his own recognizance was denied by the judge Friday, but Brian McNabb still has the option to post the $10,000 bail.
He has no prior criminal history, according to court records.
