Several people are dead today after a man went on a shooting spree on a California highway.

Details are still coming in about the rampage, which began shortly after five a.m. this morning in Ladera Ranch. There, the unidentified man shot and killed a woman before taking off in an SUV. From there, he stole a car and shot a bystander, who was treated for non-life threatening injuries. A few minutes later, the suspect committed a carjacking and fatally shot the driver on the 55 freeway before moving on to yet another carjacking, where he shot two people. One of those victims died. As police closed in on the suspect, he shot and killed himself in Orange County.

So far, the man is only described as being in his 20’s, and police aren’t sure yet as to the motive of the initial shooting.

The shootings come just days after President Obama gave a speech in Chicago regarding gun violence, after which two teenage girls were fatally shot nearby in two separate incidents.
