Wayne County prosecutors on Wednesday

against an 18-year-old Huron High School student whose 14-year-old accuser

.

Maria Miller, a spokeswoman for prosecutor's office, said the case could not proceed "because the sole evidence ... was the complainant."

The case began to make headlines last month

of Samantha Kelly, an underclassman at the New Boston high school who accused senior Joe Tarnopolski of rape. A police report filed shortly after the incident described the encounter as consensual, but Kelly later said it was

.

Tarnopolski was charged with third-degree criminal sexual conduct -- statutory rape -- but allowed to return to school, and Kelly said fellow classmates mocked her for making the accusation. "All the seniors, they're making fun of me. 'Oh, It's Joe's mistake,'" she said in October. "I have girls that want to beat me up because of him."

Kelly took her own life Tuesday, hanging herself after reportedly writing a message on her bedroom wall that included the date of her alleged rape. Family members responded with mixture of grief and anger, directed both toward Kelly's classmates and school administrators, who said

if she felt threatened.

"My daughter's dead because nobody wanted to listen to her, and the people who should have stood up for her didn't," Kelly's mother, June Justice,

. "I want to know how they're sleeping. I want to know because I was up all night with all three of my boys, and I couldn't sleep a wink. I probably won't sleep for a long time."

While his father previously refused to discuss details of the case, noting only that his son was emotionally distressed about the accusations, Tarnopolski shared his thoughts on Twitter over the past several weeks.

, the teen told Fox 2 the original report report was "a f****** lie" and wrote that "All girls are, are liars and backstabbers! I hate you all. Way to ruin my life. Seriously, now this will be on my record for life."

Except it won't, a bitter pill Kelly's family is not prepared to swallow.

"It's ridiculous," her stepfather, Jeff Curry, said. "I mean, there's no reason why the charges should be dropped. The incident obviously happened. The outcome doesn't change the fact of what the guy did."

Questioned following Wednesday's hearing,

he is "sad about what happened, but there is nothing I can do about it."

Kelly's death marks the state's 9th confirmed case of school bullying leading to suicide. Long-discussed legislation that would require schools to create and adopt policies to prohibit bullying remains stalled in the state Senate and appears unlikely to head to a vote this year.
