Why Was Mark Ruffalo's Brother Shot?

Dec. 9, 2008— -- One week after a seemingly unprovoked shooting, the brother of actor Mark Ruffalo has died and two people have been arrested in connection with the case.

Scott Ruffalo, 39, died late Monday night at Cedars-Sinai Medical Center in Los Angeles, according to Beverly Hills Police Sgt. Renato Moreno.

Two people wanted for questioning about the shooting surrendered to police earlier Monday, according to the Associated Press. Shaha Mishaal Adham, 26, was arrested on an attempted murder warrant in connection with the shooting of Ruffalo.

Brian Scofield was being held on a misdemeanor traffic warrant. His role, if any, in the case wasn't immediately clear.

Jail records didn't indicate whether the pair have hired attorneys but showed that a court date for Adham had been tentatively scheduled for Wednesday.

Police last week identified Scofield and Adham as "persons of interest" in the shooting investigation. Scott Ruffalo was shot in the head Dec. 1 at his condo.

Mark Ruffalo, star of films "13 Going on 30," "Zodiac" and "You Can Count on Me," had been at his brother's bedside since the shooting, according to his publicist Jessica Kolstad.

In the wake of Scott Ruffalo's shooting, a portrait of the man emerged.

A well-known and successful hairdresser, Scott Ruffalo worked at salons in Santa Monica and Beverly Hills, including, most recently, the Giuseppe Franco Salon in Beverly Hills.

He held a license in cosmetology since 1991 and, in 2001, set up his own corporation -- Ruff Inc. -- that took in his lucrative income as a hairstylist.

"He is well-liked by everybody and knows everyone in Beverly Hills," his accountant James Leger told ABCNews.com last week. "He was a guy who really wanted to do things right, as far as I was concerned. He is one of the easiest clients I have. He's 100 percent above board and would go overboard to make sure everything is done right."

But Scott Ruffalo did have one encounter with the law. In April 2002, he was convicted of a felony charge for possession of a controlled substance for sale. A second charge, possession of a narcotic controlled substance, was dismissed.

As Beverly Hills police continued their investigation into what happened, Scott Ruffalo's shooting came as a shock to those who know him.

"It's really strange," Leger said. "This is obviously not just a break-in. Robbers don't just routinely go to Beverly Hills in the middle of the night."

Neighbor Yelena Shekhtman told ABCNews.com that the building is "very secure." Even though she lives close by, she said she heard no sounds of gunshots or a scuffle. She only knew something had gone wrong when police knocked on her door at 4 that morning.

That such violence could occur right down the hall has shaken Shekhtman. "It's not safe now, living in Beverly Hills."
