Three former employees of Metaldyne Corp. in Plymouth have pleaded guilty to plotting to steal trade secrets and sell them to industry competitor Chongqing Huafu Industry Co. of Chongqing, China.
Prosecutors said Anne Lockwood, Metaldyne’s former sales VP, and Fuping Liu, a metallurgist, hatched a plan in 2004 to share information with Chongqing Huafu regarding Metaldyne’s powdered-metal products. Lockwood pleaded guilty to stealing and forwarding to Chongqing Huafu the electronic and paper copies of documents showing Metaldyne’s costs and manufacturing processes.
Liu pleaded guilty to receiving data and participating in the conspiracy.
Lockwood’s husband, Michael Haehnel, a former Metaldyne engineer, also pleaded guilty to misdemeanor charges of unlawfully storing electronic records.
