Illinois ? The man charged with gunning down a pastor mid-sermon and then stabbing two churchgoers had marked the day as “death day” in a planner found in his home and carried enough ammunition to kill 30 people, a prosecutor said Monday.

Madison County State’s Attorney William Mudge said he had no details on the reference in alleged gunman Terry J. Sedlacek’s day planner, only that it singled out Sunday as “death day.”

Sedlacek, 27, of Troy, was charged Monday with first-degree murder and aggravated battery in the attack at First Baptist Church that killed the Rev. Fred Winters and left Sedlacek and two congregants who tackled him with stab wounds.

Neither Mudge nor Illinois State Police would comment on a possible motive or on Sedlacek’s mental state when he allegedly strode into the church shortly after 8 a.m. Sunday, exchanged words with Winters and began firing a handgun.

Sedlacek has suffered bouts of erratic behavior his family has attributed to Lyme disease.
