If anyone can relate to the victims of Sunday's violence that left four people dead at a Colorado missionary training center and a megachurch, it's the congregation of the First Baptist Church of Daingerfield, Texas.
On a fateful Sunday morning in June 1980, the sermon was supposed to be from II Timothy, where the Bible says that "in the last days, perilous times shall come."
The congregation didn't hear the sermon that day. They lived it.
A mentally ill man walked into the church during services and opened fire. When it was over, five parishioners -- including a 7-year-old girl and some men who died trying to end the rampage -- were dead and 11 others were wounded.
Alvin Lee King, who had gone to the church wearing military fatigues and carrying two assault rifles and two pistols, was pushed out of the church. He went down the street and shot himself. He survived, but later hanged himself in a state mental facility.
The Rev. Tim Wade, First Baptist of Daingerfield's current minister, said his church has regularly scheduled deacons and other men on security duty, watching for suspicious activity. Some have law enforcement experience.
The extra security measures were put in place after the 1980 shooting and remain in effect today. The church also periodically reviews its security procedures, Wade said.
"Our hearts and compassion go to those folks who are going through such a difficult time right now because we know too well what's involved," Wade said of those in Colorado.
Matthew Murray, the gunman in Colorado, fatally shot himself after the two-city rampage.
Two more memorial services are planned today in Colorado. They have regularly scheduled services tonight in Daingerfield.
