Documents: Navy Veteran Injected 2 Alaska Teens A Navy veteran who served as a medic in Afghanistan is accused of injecting two Alaska teens with drugs, one of whom died of an overdose. Sean Warner initially was charged with injecting only one girl - a 14-year-old from Anchorage who authorities say died from the fatal heroin dose. Court records show he also faces a new charge of injecting a 17-year-old with heroin the week before. In this undated file photo provided by the Anchorage police department, Sean Warner is seen.

According to family members, Warner suffers from post-traumatic stress as a Navy medic in Afghanistan.

He faces a manslaughter charge in the Dec. 22 death of 14-year-old Jena Dolstad. Dolstad's stepfather, Brett Williams, tells KTUU-TV (http://bit.ly/zjYvsa) that the girl's mother wasn't around much. He says the family had its ups and downs but Dolstad always came home. Warner's uncle, Doug Tweedie of Bend, Ore., says Warner served as a Navy medic in Afghanistan and now suffers from post-traumatic stress. Information from: KTUU-TV, http://www.ktuu.com
