Prosecutors on Monday sought an indefinite prison term in the lay-judge trial of a 28-year-old woman suspected of murdering her then husband, a wealthy businessman nicknamed the "Don Juan of Kishu," in western Japan.

Saki Sudo allegedly killed 77-year-old Kosuke Nozaki in Tanabe, Wakayama Prefecture. Kishu is the old name for the region that includes Wakayama.

The defense maintained her innocence. In her closing statement, Sudo said she wants the court to judge based on evidence.
