( CNN ) -- The mother of a Florida girl who jumped to her death announced Monday that she will sue those she believes responsible for her daughter 's suicide -- less than a week after authorities dropped criminal charges against two girls accused of cyberbullying Rebecca Sedwick . The civil wrongful death lawsuit has not yet been filed , and mother Tricia Norman did not specify the targets of the future legal action . Rebecca , 12 , died after jumping from the top of an abandoned concrete plant in September . Norman said Monday she wants to use her daughter 's suicide `` to make society a better place to live . '' `` I 'm going to make sure other children are not tormented like my daughter was , '' Norman said in a news conference in Orlando . Authorities said Rebecca killed herself after months of cyberbullying from fellow students . The abusive behavior that authorities say prompted her suicide grew from a dispute between Rebecca and a former classmate over a boy they had both dated , police said in October . Should parents be criminally liable for kids ' cyberbullying ? Authorities initially charged two girls , ages 12 and 14 , with aggravated stalking , but the charges were dropped last week . The state attorney 's office declined to comment about the dropped charges and referred CNN to the girls ' defense lawyers , who praised the decision and said there was no evidence of stalking . Police said the abuse included messages such as `` nobody cares about u , '' `` i hate u , '' and `` you seriously deserve to die . '' Rebecca had already cut open her wrists months before the jump , but survived that suicide attempt . Norman 's attorney , Matt Morgan , on Monday called on Florida lawmakers to come up with a `` Rebecca 's Law '' -- legislation that Morgan says would allow the state to file bullying charges against minors and their parents .
