Funeral services for a slain Mountain View woman _ believed to have been shot and killed by a former employee _ were held on Monday morning; at the same time, police detectives in two cities were still trying to understand why the pioneering scientist has been killed by the brilliant genetic researcher whom she reportedly had supervised for approximately a year.

Dr. Tanya Holzmayer, a genetic researcher and former vice president of Genomic Research for Menlo Park's PPD Discovery, was shot multiple times in the doorway of her home on Windmill Park Lane last Wednesday night.

Police believe that the presumed shooter, Dr. Guyang Matthew Huang, used a Dominos pizza delivered to Holzmayer's house to lure her outside. Huang appeared after she opened the door, fired multiple rounds and fled the scene.

The pizza deliveryman was unharmed as was the victim's teen-age son, Alex Rozniov, who was home at the time of the shooting. Both were witnesses but neither were considered suspects in the case, according to Jim Bennett, the public information officer for Mountain View's police department.

After receiving multiple telephone calls from neighbors hearing the gunshots, the Mountain View police arrived at Holzmayer's home, found her dead and immediately began searching for Huang

Meanwhile, Huang left the scene and called his wife to confess what he had done; his body was eventually located in Foster City, where he had been living.

Foster City Police Captain Craig Courtin said the 38-year-old Huang was found dead of a gunshot wound to the head late Wednesday night on a levee near the San Francisco Bay.

The killing is Mountain View's first murder of the year. There were three homicides in the last three years.

For almost a year, Huang worked as director of molecular biology and bioinformatics.

Both Huang and Holzmayer worked to find genetic cures to diseases such as HIV and cancer. Both also immigrated from other countries: Huang from China, Holzmayer from Russia.

According to a 1994 Seattle Times article, Huang attended Fudan university, China's equivalent to Yale University, after getting the 11th-highest score _ out of 230,00 students _ in a college entrance exam.

Huang got his Ph.D. in Molecular Biology at the University of Massachusetts at Amherst and did postdoctoral work in molecular biotechnology at the University of Washington in Seattle. Before joining PPD, he taught at Fudan and also worked other jobs in the field, including one at Oakland's Pangea Systems.

Holzmayer was also well-established in the scientific community. With PPD she co-invented a system to locate genes that suppressed types of cancers. She was also a concert pianist as well as a friendly neighbor..

Carol Mulholt, a neighbor in the planned development, called Holzmayer "outgoing and gregarious; she went out of her way to help people."

Both Mountain View and Foster City's police departments are now working together to find a motive in the shootings.
