Fans of the TV show 7th Heaven are mourning the death of Lorenzo Brino, the actor who played one of the little twins. The 21-year-old was killed March 9 when he lost control of his car and slammed into a utility pole in San Bernardino County, California. Lorenzo and his brother Nikolas—who were quadruplets—played the youngest kids in the Camden family, David and Sam, on the series that ran from 1999 to 2007.
