Ou Yang Li-hsing, 57, deputy head of the military-owned National Chung Shan Institute of Science and Technology, was found dead in a hotel room in southern Pingtung County on Saturday morning, the institute said in a statement.
Wang Chin-sung, deputy director of the Pingtung County Police Department, said police arrived at the scene and determined he had suffered a heart attack.
There were no signs of foul play, he added.
“After checking the surveillance video footage and surveying the hotel room, the police found the windows closed and did not see any signs of a break-in or struggle, nor did we find any wounds on Ou Yang’s body,” Wang said.
Ou Yang’s family said he had a history of heart disease and had a cardiac stent.
Ou Yang, who oversaw the development of various types of missiles, assumed his role at the institute earlier this year.
