A Hillsborough County woman has been cleared in the case of a fatal August shooting.

According to partner newspaper the Tampa Bay Times, prosecutors will not file charges against Vickie Rock, who came to the aid of a neighbor who was being beaten by her boyfriend.

Rock heard screams in a downstairs apartment Aug. 17 at the Grand Oaks of Riverview. Rock went to the apartment and found Daniel Robertson beating his girlfriend Cristy Vasilakos. When Rock, who was armed, told Robertson, 56 to leave the woman alone, he attacked her, according to officials.

Rock, 50, fired three shots at Robertson, who was shot once in the chest and later died.

"The evidence is insufficient to rebut the claims of self-defense or defense of others," a Hillsborough County State Attorney's Office memo states.
