The Oakland Police Department is investigating a house party shooting that left two teen brothers dead and two others injured, authorities said.
The shooting took place in the 950 block of Apgar Street just before 10 p.m. where officers tried to help two injured victims, but they died at the scene.
The other two victims were taken to a hospital for medical treatment but no details have been released about their condition.
Witnesses told NBC Bay Area the shooting unfolded during a house party where most of the people there were teenagers from Berkeley High School.
A GoFundMe identified the two deceased victims as Angel, 15, and Jazy, 17, and added they were brothers. Berkeley High School officials said they were both students there.
Martin Opsahl, who lives in the area, said that he noticed young people were hanging out at the home. As the evening went on, more people came.

“Kind of gathering and started breaking out into bickering and hostility, And before you know it, two guys just go upstairs and started shooting at each other,” he said.
Opsahl said the gunshots were unmistakable.

“About 19, 20. I counted actually,” he said.
Opsahl called 911 and told NBC Bay Area that another neighbor tried to help someone who was hurt as police arrived at the home, apparently rented just for the night.
“You never think it will get so close to home,” he said.
The Berkeley Unified School District released a statement saying they "are deeply saddened to have learned that two Berkeley High School students and beloved members of the BUSD family lost their lives."
In the statement, the district said counselors, district and school leaders will have resources available for students returning to school Monday.
A grassroots community group called "Latinos Unidos" said its members have actually worked with these two teens and their family very closely throughout the years.
The group also said it’s asking the Berkeley Unified School District to provide mental health support for students in Spanish for students as well.
NBC Bay Area asked the district Sunday night about that and it confirmed there will be counselors at Berkeley High School, who can speak Spanish and bilingual staff in their parent resource center.
There will also be a vigil Monday at 7 p.m. at Longfellow Middle School in Berkeley. The public is invited to bring candles, flowers and respect.
The shooting is under investigation.
