GONZALES — An Ascension Parish jury convicted Patrick Calvin Parker Friday night on two counts of manslaughter in a 2004 double homicide in Donaldsonville.

The 10-2 verdicts followed nearly three hours of deliberation in the Ascension Parish Courthouse Annex after a three-day trial and one day of jury selection.

Judge Ralph Tureau of 23rd Judicial District Court ordered a presentence investigation and deferred sentencing until 9 a.m. April 9. Tureau also set Parker’s bail at $500,000 on each count.

The district encompasses Ascension, Assumption and St. James parishes.

Prosecutors accused Parker, 34, then of 1005 Mill St., Donaldsonville, of fatally shooting Katrice “Sally” Bell, 23, and Albert “June” Landry Jr., 33, both of Donaldsonville, in Bell’s Nolan Street mobile home on May 11, 2004.

They also accused Parker of shooting himself in the abdomen and placing the gun in Landry’s hand to shift blame for the shootings on Landry.

Parker had believed at the time that he and Bell were parents of a 2-year-old child, but subsequent paternity tests showed Parker was not the father of the child, prosecutors said Friday.

Parker initially faced two counts of second-degree murder in the slayings of Bell and Landry and potential mandatory life sentences.
