A Massachusetts woman who failed to appear in New London Superior Court on manslaughter charges last fall because she was incarcerated in her home state on methamphetamine trafficking charges has been returned to Connecticut.

Dina Senibaldi, 28, is accused of causing the April 8, 2011, crash on Interstate 395 in Waterford that killed Lisa Delprete of North Haven and seriously injured another man. She had been free on bond and awaiting trial in the manslaughter case when police in Chelsea, Mass., arrested her on Oct. 3, 2012, on multiple drug possession and distribution charges. Connecticut authorities discovered the new arrest after Senibaldi failed to appear in court in November.

Senibaldi waived extradition from Massachusetts, where authorities agreed to release her to Connecticut despite her pending drug trafficking charges. At her arraignment this afternoon, Judge Karen A. Goodrow set her bond at $400,000 and continued the case to May 14.

State police said Senibaldi was under the influence of alcohol and was driving 100 mph when her car rear-ended a Jeep Grand Cherokee driving in the right hand lane of I-395 southbound about 0.7 miles south of exit 77 in Waterford. The Jeep flipped onto its passenger side and landed on a guard rail, trapping Delprete in the passenger seat. The driver, Edmund Davis, underwent multiple surgeries for a severe scalp laceration and facial injuries, broken ribs and a collapsed lung.

Prior to her arrest in Massachusetts, Senibaldi turned down an offer from Connecticut officials to plead guilty in exchange for a six-year prison sentence.
