Three people were shot outside of a house in the 4600 block of Argonne during a graduation party.
San Antonio police say about a dozen people were at the party when someone ran up to the party and said someone was chasing them. A short time later a pickup pulled up and opened fire on the crowd.
A man in his 30s was hit in the face and is in critical condition. A woman in her 40s and a teenage girl were also wounded and are in stable condition.
Police are searching for suspects.
