By Clive Myrie BBC correspondent in Bali

Mark Weingard arrived in Bali on Monday. He was tired and desperate.

A friend had broken the news to him that a nightclub on the holiday island had been bombed.

"He told me what had happened and I thought, I hadn't heard from Annika," Mark said.

"I knew she would call me straightaway.

She still has not called.

Mark is appealing for information on Annika

Annika Linden is Mark's girlfriend and they are engaged to be married. She was in the Sari nightclub when it was attacked. She is still missing.

At one hospital, Mark checks her name against a register of all those who are dead or injured. She is not here.

He has printed cards and posters appealing for information. Another friend, Daniel Miller, is also missing.

Harrowing mission

There are more frantic phone calls. The strain is beginning to show.

Mark tries calling hospitals in Australia, hoping his missing fianc�e and friend have been air-lifted out.

"There is no chance she is in Perth or Darwin," Mark said.

Others are also searching for loved-ones

Going to the morgue is the last thing he wants to do but he knows he might have to.

There, bodies recovered from the wreckage are kept cool in the blazing heat.

But there are too many bodies and too few blocks of ice. The stench of death hangs everywhere.

There may be dozens of bodies lying on the floor inside but few will be laid to rest any time soon. There are coffins on standby, but identifying so many of those who died is proving difficult.

At another hospital, Mark Weingard checks more lists of names of those injured.

There is still no sign of Annika.

He later tells me he is running out of hope, that he now believes she is dead. But he will go on looking for a little while longer.

Others are flying into Bali hoping to get information on missing friends and relatives but for most it will be a fruitless journey. It is thought there are still many buried within the wreckage, perhaps forever.
