ARLINGTON, TX --Police say robbery may have been the motive in an attack at a Texas church that left the pastor dead and an employee hospitalized. Arlington police said Friday that items were missing from NorthPointe Baptist Church but wouldn't give details. Police continue searching for the injured ministry assistant's vehicle, which was believed stolen after the Thursday attack. Church members described the Rev. Clint Dobson as a dynamic pastor who always had a smile and hug for them as they walked into the sanctuary before services. NorthPointe is a satellite church of First Baptist Church of Arlington, where the Rev. Dennis Wiles says both congregations are in mourning. Wiles says Dobson had a warm demeanor and wonderful sense of humor. He says Dobson was a great communicator and preacher.
