NEW LENOX, Ill. — Members of the 12-person Christopher Vaughn jury focused mainly on the case's physical evidence before coming to their conclusion of his guilt, one jury member said Friday.

In a phone interview, Steve Sulikowski, a 24-year-old from New Lenox, described his experience serving as part of the jury that took less than an hour Thursday to convict Vaughn on first-degree murder charges in the shooting deaths of his wife, Kimberly, and children Abigayle, 12; Cassandra, 11; and Blake, 8, on June 14, 2007, in Channahon.

While ready to bring the trial to an end, Sulikowski said the group's first interest in entering the jury room at about 3:30 p.m. Thursday wasn't to start deliberations — it was a delayed lunch.
