I don't think so. Suppose you capture an elephant. It escapes from its enclosure and causes havoc. Was the elephant designed by you to cause havoc? No. Especially, because you didn't release it on purpose.

AFAIK the genome of the virus has been analysed to the point where it has been determined that it could not have been engineered in a lab.
