Prosecutors are expected to charge a retired Honolulu police major with negligent homicide in connection with the death of a 49-year-old federal court employee who was hit by a pickup truck while jogging in Mililani in February.

Charles T. Duncan, 73, of Mili­lani was arrested Friday morning on a criminal complaint in connection with the Feb. 5 death of Mili­lani resident Shari Afuso. The prosecutor’s office said formal second-degree negligent homicide charges are expected.

Duncan, who served 32 years in the Hono­lulu Police Department and was a watch commander before he retired, has declined to comment on the case.

Police in February said Afuso was jogging in a marked crosswalk around 7 p.m. when she was hit by a 2012 Chevrolet pickup truck turning left onto Kuahe­lani Avenue from the southbound lanes of Mehe­ula Parkway.

Paramedics took Afuso in critical condition to the Queen’s Medical Center, where she died. The Honolulu medical examiner said she died from cranial cerebral injuries due to blunt force trauma.

Afuso, mother of two teenagers, was courtroom manager for U.S. District Judge Kevin Chang. She jogged regularly and was a few blocks from her home when she was struck by the truck.

She and her husband, Mark, had celebrated their 20th wedding anniversary a few days before the accident.
