The man accused of a deadly shooting spree outside two Jewish community sites in the midwestern U.S. state of Kansas made his first court appearance Tuesday.

The suspect, 73-year-old Frazier Glenn Cross, was charged with murder. If convicted, he could face the death penalty.

Cross is being held on $10 million bond. His next court appearance is scheduled for April 24.

Federal prosecutors say they are pursuing federal hate crime charges and will present evidence to a grand jury soon. That, too, could be a death penalty case.

Cross is a Vietnam War veteran and a longtime white supremacist and Ku Klux Klan member. He shouted a Nazi slogan at television cameras as he was arrested after Sunday's killings.

U.S. Attorney General Eric Holder is asking Congress to approve $15 million in funding to train police officers to handle active shooters.

The Justice Department says Holder is making the request in the wake of the Kansas incident and the April 2 shooting at the Fort Hood military base in Texas, which killed four people.

In a video message on the Justice Department website, Holder said the training is critical because patrol officers who arrive first on the scene are increasingly being relied on to respond directly to shooters rather than to wait for SWAT teams.
