Honolulu police are asking for help identifying two hit-and-run drivers, one case a serious injury and the other a fatal crash, both bad news for public safety and both still unsolved.

• In Mililani on November 7, a silver Toyota sedan hit a man crossing legally in a marked crosswalk, then drove off without stopping or helping; a bystander helped the victim until paramedics arrived.
• No cameras caught that crash, so police need witnesses to come forward with the plate number or a description of the driver.
• In Waipahu, a light-colored van hit and killed a 25-year-old woman walking in the road outside a crosswalk in the middle of the night on October 11, then kept driving without stopping.
• Investigators have surveillance footage of the van and are highlighting unusual features, a company logo on the back, rear-mounted license plate, and lower-set tail lights, to help identify it.
• Police are reminding drivers and pedestrians to stay alert near crosswalks and are offering a reward of up to $1,000 for tips leading to an arrest in either case.

Outlook: Police are relying on public tips and the van's surveillance footage to identify suspects, with no arrests reported yet in either case.
