Officers now believe the victims may have been stabbed while attending the same party in southeast Fresno.
A man in his late teens arrived to CRMC with injuries just after 6 am.
Just minutes later, a woman also came in with stab wounds.
The woman told police she was stabbed while attending a party at Alta and Hazelwood.
Police say the woman's injuries were superficial and the man is expected to survive after undergoing surgery Sunday morning.
Officers are now investigating the scene of the party.
