In the first accident, Hodges, 43, was killed when she was struck by a pickup at 5:20 a.m. on Kalaniana'ole Highway, near Waimanalo Beach Park.

The Honolulu husband and wife, ages 80 and 81, were killed at 10:10 a.m. in a one-car collision in the Kapalama post office parking lot.

Frank Rodrigues was driving the light blue Honda Civic and had just dropped off mail in the drive-through mailbox when the car suddenly accelerated, climbed a sidewalk and crashed into a wall on the diamondhead end of the lot. He was not wearing a seat belt, but his wife was, said traffic investigator Sgt. William Baldwin.

The husband died at The Queen's Medical Center and Daisy Rodrigues died at Kuakini Medical Center.

Police have not determined why the car accelerated, although one witness told police that the couple appeared to be arguing. Baldwin asked anyone who witnessed the accident to call him at 529-3136 or 529-3527.

Baldwin said the Waimanalo accident happened when Hodges, 43, tried to cross from the mauka side, between Pu'uone and Olu'olu streets.

A 1998 Ford Ranger pickup truck heading toward Makapu'u, driven by a 56-year-old Waimanalo woman, struck Hodges, who died at Castle Medical Center.

The driver was not speeding or under the influence of alcohol, police said.

Police do not classify the Kalihi accident as a traffic fatality; the Waimanalo accident raises the O'ahu traffic death toll to 17, compared to nine fatalities last year.

Yesterday's traffic mayhem also included an accident on the Likelike Highway, near Kalihi Street at 10:23. A woman riding a moped was taken to Queen's, where she remains today in guarded condition.
