The Travis County District Attorney’s office is considering reviewing the case of a man convicted of killing his ex-girlfriend.
Investigators may take a closer look at the circumstances surrounding Natalie Antonetti's 1985 murder in Barton Hills. The cause of death in that case has similarities to two other murders within a 27-month time period in the mid 1980s
Former Austin music studio owner and ex-boyfriend Dennis Davis was convicted in April of last year in Antonetti's murder. He was sentenced to 36 years in prison.
Antonetti's case went unsolved until Travis County prosecutors received new information leading to Davis' arrest. He was residing in Nashville at the time of his arrest.
Crime scene evidence shows Antonetti died of blunt force trauma.
Last year, 57-year-old Mark Norwood was charged in the 1986 death of Christine Morton. The handyman was arrested in November in Bastrop County, one month after Morton's husband Michael was released from prison. Michael Morton previously spent two decades behind bars for his wife's murder--a crime he didn't commit.
DNA evidence found at the scene linked Norwood to the murder. That same DNA also connects him to the 1988 murder of Debra Baker, although he's not charged yet with that crime.
All three women lived within 12 miles of Norwood's home at the time.
The district attorney's office say similarities in all three murder cases is what could prompt a review in the Antonetti case.
