KNOXVILLE, Tenn. (AP) — A Knox County jury will decide the fate of one of three suspects charged with killing three people at a homeless camp in Knoxville.

The Knoxville News Sentinel reports (http://bit.ly/1pA3Wsg ) 30-year-old Joshua Cool is standing trial this week on three counts of first-degree murder in the April 2013 slayings of 28-year-old Collin Colbert, 29-year-old Ryan Gorney and 32-year-old Grace Standridge.

Prosecutors say the killing spree began with a clash that led to the fatal attacks.

Two other suspects, 24-year-old Hope Carol Warvi and 31-year-old Brandon Roberts have already confessed their respective roles in the killings.

Warvi struck a deal to lesser murder charges in return for her testimony this week. Roberts pleaded without a deal and is serving life.

Jurors begin deliberations Thursday.
