DETROIT (AP) — A former General Motors engineer and her husband have been convicted of stealing trade secrets about hybrid technology for possible use in China.

Shanshan Du and Yu Qin (CHIN) were found guilty Friday by a federal jury in Detroit after a trial that lasted weeks. The government claimed Du sought a transfer while at GM to get access to hybrid car technology and then copied documents until she accepted a severance offer and left the company in 2005.

Prosecutors told jurors that GM trade secrets were found on at least seven computers owned by the Oakland County couple. The government doesn't believe the information ever made it to China.

Du, Qin and their attorneys declined to comment after the verdict was read. Du was acquitted of wire fraud.
