St. Rose of Lima Church in Newtown, Conn., was evacuated Sunday after state police responded to a threat during noon mass—and rehearsal for the Christmas pagent. Officials cleared the church by 2 p.m. More than a dozen state troopers armed with assault rifles entered a home next to the church, said NBC reporter Audrey Washington. A SWAT team began a sweep of the church after the evacuation. The town is still reeling after 20 children and six adults were killed Friday when Adam Lanza opened fire at a local elementary school. His mother was also found dead in her Newtown home Friday.
