A Rhode Island man has been sentenced to two life terms plus 35 years after being convicted of the 2011 killing of a 17-year-old girl. Superior Court Judge Netti Vogel imposed the sentence Thursday on Leron Porter, 33. A spokeswoman for the attorney general’s office said Porter will not be eligible for parole until he is in his 80s. He was convicted of second-degree murder in December in the death of Tiphany Tallo in Providence. Prosecutors said Porter and several relatives confronted Tallo’s sister in May 2011 after she had an argument with Porter’s sister. Authorities said Porter shot and killed Tallo when she tried to help her sister.
