( CNN ) -- A federal jury on Monday convicted an Arkansas doctor in a February 2009 car bomb attack on the head of the state 's medical board , according to the U.S. attorney 's office . Randeep Mann will face up to life in prison when he is sentenced later , said Cherith Beck , spokeswoman for the U.S. Attorney 's Office for the Eastern District of Arkansas . Court records show Mann 's trial began July 6 . Jurors convicted Mann on seven counts , including using a weapon of mass destruction against a person and property , and using an explosive resulting in personal injury . Dr. Trent Pierce , a family practitioner , suffered serious injuries in the attack and lost an eye , but survived . He was leaving his home in West Memphis , Arkansas , headed to his clinic when a bomb went off as he approached his Lexus hybrid SUV . The blast , heard a mile away , threw Pierce 6 feet into a flower bed . KARK reports on the Arkansas bombing . Mann , whose specialty was internal medicine and pain management , had `` multiple disciplinary matters '' before the state medical board , federal prosecutors said . Early in the investigation , authorities focused on cases before the board , which oversees licensing of those in medical professions and can discipline professionals by suspending or revoking their licenses in some cases . Mann 's wife , Sangeeta `` Sue '' Mann , was convicted of conspiring with her husband to conceal evidence and obstruct the investigation , Beck said . She will face up to 20 years in prison when she is sentenced . Authorities said Mann was interviewed by federal agents on the day of the bombing and showed them `` at least one grenade launcher he legally owned . '' However , he was not arrested until a month later , when city employees found partially buried `` high explosive rounds designed to be fired from a grenade launcher '' in a wooded area of London , Arkansas , authorities said . Jurors convicted Mann of possession of 98 unregistered grenades and two counts of possessing machine guns , but acquitted him of possessing an unregistered 12-gauge shotgun . Sangeeta Mann was acquitted of lying to a grand jury investigating the unregistered firearms .
