Tim Roche, a tenacious South Florida newspaper reporter who became the first Florida journalist ever to be jailed for refusing to name a news source, died early Friday at a Tampa-area hospice after suffering a series of strokes. He was 38. Roche was 22 when he broke a series of stories about a controversial child custody case for the Stuart News. When prosecutors pressed him to name the souce who leaked sealed court documents, Roche refused. Two years later, in 1993, having exhausted all appeals, Roche surrendered to the Martin County Jail, where he served 18 days of a 30-day sentence. The New Mexico native also was among a team of St. Petersburg Times reporters who were finalists for the prestigious Pulitzer Prize for a series of stories that exposed the lavish lifestyle of a Pinellas County minister, Henry Lyons, who was later convicted of fraud.
