“Hello, I am calling because I see a gentleman who looks very similar to the suspect in the Kupfer stabbing in L.A.,” the caller states. “I’m in Pasadena…He just walked past the corner of Green and Terrace, in Pasadena.”

The Los Angeles Police Department announced the arrest Wednesday and said the Pasadena Police Department detained Smith, 31, at around 11:50 a.m. near Fair Oaks and Colorado Boulevard.

The caller said he saw Smith in a black hoodie, dark sweatpants and the distinctive backpack he was seen wearing in surveillance video showing him buying a vape pen at a Los Angeles 7-Eleven store just 30 minutes after the killing.

Smith, who has a rap sheet spanning two coasts, initially gave a fictitious name, the source said. The LAPD sent its fugitive unit with a fingerprint reader to Pasadena and confirmed Smith’s identity with the device.

The LAPD received more than 1,000 tips since launching its investigation into the Jan. 13 stabbing death of the UCLA graduate student, the source said.
