A police spokesman the day before had said investigators were still trying to determine whether multiple shooters were involved, but Stockton City Manager Harry Black during the Tuesday news conference said detectives were searching for "what looks like a single person who committed these crimes," according to NBC Bay Area.
Police also declined to say whether all seven shootings were linked to the same gun.
The San Joaquin County's Office of the Medical Examiner on Monday released the Stockton victims' identities: Paul Yaw, 35, Salvador Debudey Jr. 43, Jonathan Hernandez Rodriguez, 21, Juan Cruz, 52, and Lawrence Lopez Sr., 54.
Police said investigators do not believe the victims were targeted for their race, The New York Times reported.
The city of Stockton is offering a $75,000 reward for information leading to an arrest. Stockton crime stoppers and a local construction company owner are offering an additional $10,000 each, according to police.
The conventional definition of a serial killer is someone who has murdered three or more people in incidents exhibiting commonalities.
