Investigators have yet to identity the assailant or assailants responsible for the attacks, and it remains unclear if the crimes are related, according to the OPD.

The Oceanside Police Department on Tuesday warned local homeless population on the recent uptick in violence. Two of them were killed just this past weekend.

Two of the attacks, the first and the most recent, involved people living in the riverbed in Oceanside, Oceanside police chief Kedrick Sadler said; a third victim was found near the railroad tracks.

Two men are dead and another is severely injured following three violent attacks on homeless individuals in North County over the past two-and-a-half weeks, authorities said.
