The woman accused of killing a man in an Anchorage hit-and-run collision last year made her initial court appearance Thursday afternoon.

Adanna Francis, 19, faces charges including second-degree murder, manslaughter, DUI, leaving the scene of an injury accident, reckless driving, and driving with a cancelled or revoked license. She was arrested Thursday morning by police and held at the Anchorage jail.

Francis is accused of killing 40-year-old rollerblader Paul Winter in a June 5, 2018 collision on Cordova Street between 9th and 10th avenues. Police said at the time that witnesses had spotted a black Ford Expedition being driven recklessly, headed south on Cordova.

Officers had stopped the SUV and questioned Francis, who was at the wheel, but didn’t announce any arrests pending further investigation.

On Thursday, Francis remained silent during an initial appearance at the Nesbett Courthouse in Anchorage. A not-guilty plea was initially entered on her behalf.

Assistant District Attorney Dan Shorey, who helped prosecute the case, said Thursday that he couldn’t discuss some details until they were formally filed in court documents. He attributed the delay in filing charges against Francis to an extensive investigation, which determined that Francis was impaired by a "controlled substance" he couldn't yet publicly name.

“That involved toxicology screening both at the Alaska state crime lab and the Washington State Patrol crime lab – that took until the end of December,” Shorey said.

In addition, investigators worked with the Ford Motor Company to examine whether there were any mechanical issues with Francis’ SUV involved in the collision.

“There was nothing wrong with her Expedition,” Shorey said.

Francis was ordered held Thursday on a total of $150,000 bail. Prosecutors are likely to file documents containing more details in the case during a future bail hearing, Shorey said.
