LOS ANGELES (AP) — A 75-year-old woman was convicted Thursday of murdering a homeless man to collect life insurance, but the jury said it was deadlocked on another murder charge and a conspiracy count.

The judge ordered more deliberations in an effort to conclude a trial that has spun a bizarre tale of a murder-for-profit scheme carried out by two elderly women.

Olga Rutterschmidt was convicted of the first-degree murder of Kenneth McDavid, 50, a day after she was found guilty of conspiring to murder him for financial gain. Her 77-year-old co-defendant, Helen Golay, was convicted Wednesday of murdering McDavid and Paul Vados, 73, and counts of conspiracy in both killings.
