Prosecutors on Thursday indicted two doctors over the death of a terminally ill 51-year-old woman with ALS, alleging they took part in her medically assisted suicide last year with her consent.

Yoshikazu Okubo, 42, and Naoki Yamamoto, 43, were arrested in July for allegedly giving Yuri Hayashi a lethal dose of a sedative drug at her home in the city of Kyoto last November. Before her death, the woman had transferred ¥1.3 million to Yamamoto's bank account.

The disease Hayashi suffered, amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, is a progressive neurological disease with no fundamental treatments established. Afflicted since 2011 and hardly able to move, she is believed to have wished to die by euthanasia.
