While Scott Ruffalo is still in critical condition at a Los Angeles hospital after suffering a wound to his head last week, police now have two suspects in custody.

News of the attack on actor Mark Ruffalo’s brother came as a shock last week, with Los Angeles police giving few details on what had happened. What the media was told at the time was that Scott Ruffalo, 39, had been shot in the head at his home on North Palm Drive in Beverly Hills, on December 1.

The well-known hairdresser, who moved from his native Kenosha, Wis. to San Diego with his family in his youth, has worked in salons in Santa Monica and Beverly Hills.

At the time, Jessica Kolstad, publicist for Mark Ruffalo, would only say the actor’s younger brother had been shot in the head at his Beverly Hills condominium early Monday morning, at about 1:40 a.m.

Beverly Hills police spokesperson Lt. Tony Lee said “suspicious activity” had taken place at the location and time of the shooting and that that detectives were investigating whether the shooting was homicidal, accidental or suicidal.

A few days later, the Beverly Hills Police Department identified two people as “persons of interest” in the shooting and said they wanted to question the pair, Brian Scofield and Shaha Mishaal Adham, as part of an attempted murder investigation. Scofield, 29 years old, and Adham, 26 years old, live in the Los Angeles area.

By then, Ruffalo’s publicist had also revealed his younger brother was clinging to life.

Adham turned herself in to Beverly Hills police on Monday, according to media reports. An attempted murder warrant for her arrest had been issued earlier on Monday. Adham is being held without bail.

Scofield, apparently a friend of the woman’s, arrived at the police station with Adham. He was booked for a misdemeanor traffic warrant for past violations.

Police have not revealed a possible motive for the attack.

Scott Ruffalo has had problems with the law before, as he was convicted in 2002 for possession of a controlled substance with intent to sell. He is married to Luzelena Ruffalo, a fellow hairdresser, and is stepfather to her daughter, Lucinda. He remains hospitalized.

Mark Ruffalo has starred in films such as The Last Castle, 13 Going on 30, Eternal Sunshine of the Spotless Mind, All the King’s Men, Zodiac and this year’s Blindness.

Scott Ruffalo is uncle to the actor’s children with Sunrise Coigney, son Keen, 7, daughter Bella, 3, and daughter Odette, 1.
