Jurors were unable to reach a verdict on Friday over a former ice cream truck driver in Hillsborough County accused of shooting six people, killing two brothers in 2010. Retrial started in March after a judge declared a mistrial three years ago. Keetley is accused of committing the crimes outside of a Ruskin home on Thanksgiving Day in 2010. Earlier that year, investigators said Keetley was beaten up, shot and robbed while working from his ice cream truck and then became obsessed with revenge. However, prosecutors said he went after the wrong people. Keetley is charged with two counts of first-degree murder in the deaths of Sergio Guitron and Juan Guitron — and the attempted murders of Daniel Beltran, Gonzalo Guevara, Ramon Galan Jr. and Richard Cantu.
