The ruthless world of tabloid photography has taken another victim. TMZ reports that Hollywood paparazzo Chris Guerra was killed yesterday in Los Angeles, while tailing Justin Bieber’s Ferrari. The 29-year-old photographer was hit by oncoming traffic when, after seeing Bieber’s car get pulled over by police, he walked onto the street hoping to get a shot of the Canadian pop-superstar. Guerra had been tailing Bieber all day when he saw the singer’s car leave the Beverly Hills Four Seasons.
