Police: Iowa inmate attacks fellow prisoner

CORALVILLE, Iowa (AP) - Authorities say an Iowa man imprisoned for killing two store clerks has been accused of trying to kill another inmate.

According to the Globe Gazette (http://bit.ly/1zY6JxH ), a criminal complaint states that 21-year-old Michael Richard Swanson slashed a fellow inmate in the neck at the Iowa Medical and Classification Center in Coralville on Nov. 13. The victim required stiches for 15 cuts.

Swanson is charged with felony attempted murder.

Swanson was convicted of killing 47-year-old Vicky Bowman-Hall while she worked at a convenience store in Algona in 2010. He was convicted of killing 61-year-old Sheila Myers on the same night while she worked at a convenience store in Humboldt. Swanson was 17 at the time.

He was serving two life terms, but his sentence was commuted by Gov. Terry Branstad, which allows him to seek parole after 60 years.
