I am deeply sorry to inform the passing of my dear friend Andrew
Grebneff from New Zealand. Below is the message I got this morning.
Marcus Coltro

Dear staff and senior students of the Department of Geology:
I am sorry to pass on a message received about 4 pm this afternoon
Thursday: that our paleontology technician Andrew Grebneff has been
found dead in a hotel room in Mexico. Andrew worked last week until
Wednesday, and then said he'd take a few days off. He had the weekend
with his family, somewhere out of town, but returned home early,
ostensibly to do field work. He didn't return home on Monday night,
and on Tuesday was tracked to Los Angeles. From there, he sent a brief
message saying he would not be back in New Zealand.

Andrew Grebneff worked with me as a fossil preparator since 1985, on
rolling short term contracts. He had consuming interests in
paleontology, and in the study of molluscs. He was an exceptionally
skilled preparator, meeting the highest international standards. His
wife Kala, and two teenage children, can be contacted at 38 Crosbie
Street, Mornington, Dunedin; tel 453 4436. Sincerely Ewan -- R. Ewan
