Jena Dolstad, 14, of Anchorage, Alaska, has died after fighting for her life for six days, according to local police reports. The teenage girl was allegedly injected with heroin, at a drug party gone bad.

According to court filings, Sean Warner, a Navy veteran, and two friends of his - along with Dolstad - were at Warner's residence. The men were sharing a gram of heroin when Dolstad reportedly said she wanted to try the substance. However, she apparently also said she didn't want to inject herself and asked Warner to do it for her. Tragically, he couldn't find the vein at the first attempt and wound up injecting her with 25-30 units, in multiple attempts.

The two friends who witnessed the incident told police they found Dolstad lying unconscious on her bed, the next morning. The felt for her pulse, sat her up and grew concerned, both at her condition and Warner's ambivalence, an AP report said, quoting court papers.

Apparently, Warner did not initially call 911 since he feared authorities would book him for drug use. Instead, he reportedly tried to treat Dolstad with a drug called Suboxone, which only worsened her condition. He did later call emergency services but Dolstad was experiencing convulsions by then, the AP report added.

Dolstad was found to have a cocktail of heroin, cocaine and methamphetamine in her body and suffered heart and brain damage which eventually lead to her death.

Sean Warner now faces the additional charges of manslaughter, in addition to being charged with the delivery of controlled substances to a minor and contributing to the delinquency of a minor, along with evidence tampering.
