No,, not premeditated murder. A reckless act without intent is manslaughter. Theres no evidence he wanted her dead. He was a 21 year old kid, they make mistakes. Sometimes very heartbreaking ones. They think they can all drive at Daytona, handle a gun like Delta Force, etc. Sometimes they learn bitter lessons the hardest way.
Thers’s enough real murderers to go after. This was a sad accident from immature gun handling.
Then why did he change his story?
