ZAGREB, Croatia (AP) _ Documents may have been lost through time and memories may be locked in the dark corners of the mind, but there is ample evidence to convict a former concentration camp commander of war crimes, the prosecution said Tuesday.

In closing arguments, prosecutors asked a panel of seven judges to impose the maximum 20-year prison sentence on Dinko Sakic for his alleged role in the deaths of 2,000 people.

Sakic, 77, ran the Jasenovac camp for about six months in 1944. Tens of thousands of Serbs, Jews, Gypsies and anti-fascist Croats were slaughtered at the site, which operated from 1941-1945.

He is charged with ``maltreating, torturing and killing detainees'' and allowing his subordinates to do the same during his tenure as commander. The trial began March 15 after Sakic was extradited from Argentina.

``The defendant was aware that Ustashe soldiers (Croat fascists) starved, tortured and killed at their whim,'' prosecutor Radovan Santek said. ``He allowed and tolerated without sanction those crimes and even participated in them personally.''

At least four witnesses testified to seeing Sakic empty his gun into the head of a former inmate from point blank range after a mass hanging of victims.

Sakic was extradited after an April 1998 interview on Argentine television in which he admitted to running the Jasenovac camp.

He attributed the fatalities there to a typhus epidemic and ``natural causes.'' He stuck to those claims during court proceedings, accusing witnesses of falsehoods, exaggeration and hearsay.

There are no exact figures for the number of victims killed at Jasenovac, 60 miles southeast of Zagreb. Some Croat historians put the number at 35,000 and some Serbs, who made up the majority of the victims, at 700,000. The U.S. Justice Department said up to 125,000 people might have died there.
