Authorities say Ricardo Chaney was killed in a March 19 shootout with a Fort Bragg, Calif., police officer.
The Register-Guard reports ( http://is.gd/npAU6Y) Eugene police spokeswoman Melinda McLaughlin said Tuesday that one case under review is a March 11 armed robbery at an adult shop. An armed man fled after stealing cash.
McLaughlin said other, unspecified crimes are getting a fresh look as well.
Police believe the violence started in Eugene with the fatal shooting of a 79-year-old retired University of Oregon anthropology instructor. The police spokeswoman has said Chaney knew George Wasson's family.
Police say Chaney carjacked a BMW and headed for California, where authorities believe he fatally shot Mendocino County Deputy Ricky Del Fiorentino before being killed by another officer.
