A man charged in a crash that killed an off-duty Wichita police officer and his young son last year is set to stand trial. 35-year-old James Dalrymple has been charged with two counts of involuntary manslaughter after he pulled out in front of 37-year-old Stacy Woodson and his nine-year-old son, who were on a motorcycle. Woodson was a 16-year Wichita police veteran who worked in the motorcycle unit. It was suspected that Dalrymple was driving under the influence when the accident happened.
