In his first interview since killing Hwange National Park’s iconic black-maned lion, Cecil, in July, Minnesota dentist Walter Palmer announced Sunday night he would be returning to his practice later this week.

CNN reports that, according to a senior park official, Cecil the lion’s brother Jericho, who is also a lion, was killed on Saturday in Zimbabwe’s Hwange National Park. Others have called this account into question. [UPDATED.]

Authorities in Zimbabwe are searching for a Spaniard who is suspected of paying park guides €50,000 for the opportunity to kill Cecil the lion, The Guardian reports. Cecil, star attraction of the Hwange national park, was found skinned and headless on the edge of the park earlier this month.
