THE MERCURY reported last week on the wrongful death lawsuit filed by the daughter of Daphne Mosley, a 53-year-old HIV-positive woman who died in 2014, unconscious and allegedly ignored on the floor of the Portland residential care facility she was placed in by the state.

A county investigation backs up that version of events, we've learned. Officials looking into the incident found ZR Pacific Care Home and its owner Zahra Rahmani failed "to adequately train, orient, or provide sufficient oversight to staff." The county fined Rahmani $1,000 and ruled one staff member "is never to be left alone with residents."

Mosley died when Rahmani was out shopping, leaving a lone employee to look after residents. The caregiver ignored Mosley on the floor, the report says, and after hours finally called Rahmani. Rahmani called another resident to check on Mosley, and that resident finally called 911.

In the report addressed to Rahmani, the county wrote it "finds a resident in your adult care home did not receive the care, supervision, or services necessary to maintain [her] physical health when, on May 10, 2014, [she] was left on the floor without assistance for several hours... The inaction of your staff created a risk of serious harm to the resident." DOUG BROWN

FEDERAL OFFICIALS still aren't ready to share their plan for cleaning up Portland's toxic riverbed.

The US Environmental Protection Agency announced last week it's once again delaying a "proposed cleanup plan" for more than 2,000 acres of polluted muck at the bottom of the Willamette. After repeatedly pushing back the plan's release, the agency now says it will be ready June 8.

The report is a hugely important step, more than 15 years after the Portland Harbor was listed as a federal Superfund site. It sets a baseline for discussions about how much of the river will be actively cleaned up, and how much will be left to slowly recover on its own.

But the tardiness of the proposed plan might present a problem officials have looked to avoid: It will be hard to get the thing finalized before January 2017. That means there's a risk the new US president could throw the process into chaos when he or she takes office next year. DIRK VANDERHART
