A teen who fatally shot herself in the stomach — stunning friends and family who initially doubted it was a suicide — was upset over the loss of her “first love” and had threatened to kill herself, her mother revealed in an interview.

Jennifer Riggan said her 17-year-old daughter, Hannah Green, was likely seeking the attention of her boyfriend when she shot herself Saturday night in Amelia, Virginia, the Richmond Times-Dispatch reported.

“I do know that she was threatening, if he didn’t come back, that she would kill herself,” Riggan told the newspaper. “But I don’t think she purposely wanted this.”

The mom said that the Amelia High School student with plans to attend college in the fall may have pulled the trigger but was not “thinking out” the situation.

“I have no reason to believe that my daughter didn’t want to live,” Riggan said. “I have no reason to believe she was a troubled child and wanted to commit suicide.”

The couple was fighting before Green, a softball standout, allegedly shot herself in the stomach, according to her mom.

“It was young love, it was her first love — her high school boyfriend,” Riggan said. “This was a struggle within herself and the loss of her first love.”

The wounded teen was conscious and able to talk when officers found her Saturday night in a storage facility, authorities said.

She was rushed to Chippenham Hospital, where she later succumbed to her injuries, according to police.

The state medical examiner ruled Tuesday that her cause of death was a suicide — stunning loved ones of the “always happy” teen, according to WTVR.

Officials said that there was alcohol in her system when she died.

“I just believe it was teenagers, alcohol and guns — and a fight,” her mom told the Richmond Times-Dispatch.
