Daniel Christopher Yealu, 29, was shot and later died after an April 7, 2014, attack inside the Wilshire Division station in Mid-City. According to reports, he walked up to the front desk and fired a Glock pistol at two officers; one officer was wounded and both officers returned fire. Yealu was hit multiple times, hospitalized in critical condition, and pronounced dead on April 24, 2014 at 2:53 p.m. He had been charged with two counts of attempted murder of a peace officer before his death.

Investigators found Yealu had more weapons in and around his car parked outside the station, including a heavily modified AK-47, extra magazines, a 9-millimeter handgun, a semi-automatic Sig Sauer, an AR-15-style rifle, an SKS, and a 12-gauge shotgun. About 20 people were attending a community meeting nearby when the shots were fired; the station’s doors had been left open for the meeting. Yealu had earlier applied to become an LAPD officer and held expired security and firearm permits.

What details about the attack or the station’s security might help explain how Yealu gained entry that night?
