Administrators say 28 students and five staff members who were very close to Diane Romero stayed home Friday.
Others mourned together on campus. Romero was found dead in her family's pool Thursday morning. Her husband, Rudolfo, is a school bus driver. He was found in critical condition.
Police say both of them had been stabbed. The associate superintendent visited Peterson Elementary Friday, to help students deal with the tragedy. He says some cried on the playground, while others just wanted to talk. "A number of them came up to me wanting to talk about what happened, and wanted to write cards, told me that they were going to do something for the family," said Greg Spicer.
An autopsy was performed on Diane Romero's body Friday, but the results will not be released until next week.
