SEATTLE (AP) — The FBI has boosted a reward to $20,000 for information leading to the arrest of a man wanted in a slaying in Washington state nearly two decades ago.

Authorities in Pierce County said Liban Abdulkadir Sheikh shot Ricky Sinclair six times in Lakewood, near Tacoma, in November 2002 to punish Sinclair for intervening in a domestic disturbance involving Shiekh’s friend. Sheik was charged with first-degree murder and with assault for shooting and wounding his friend’s former girlfriend.

The FBI says Sheikh, a 43-year-old Somali national, has been a fugitive since the shootings. The agency’s Seattle field office announced Thursday it had increased the reward for his arrest from $2,500 to $20,000.

The authorities said Sheikh lived in the Seattle area at the time and was later reported seen in Minneapolis, Minnesota.

They also said he has connections in or may have traveled to Columbus, Ohio; Surrey, in the Canadian province of British Columbia; Amsterdam; Oslo; London; or Somalia.
