Both were taken to the hospital where they were pronounced dead.
Seese, who according to his bio did his undergraduate work at YSU, was confronted at his auto by Michael Wood, who was carrying a handgun.
Two people are dead after police said a man walked up to a doctor in an OH hospital parking lot, shot him, then turned the gun on himself Monday.
Police say this was an isolated incident and there was no threat to anyone else. Police noted he was affiliated with the Massillon medical center where the shooting occurred but that his practice was in Perry Township.
Seese, referred to as "Skip" by those who knew him, was a practicing cardiologist in Northeast Ohio since 1992, according to Fox 8.
Seese had 13 children ranging in age from 5 to 32, according to his bio.
Authorities said the gunman shot Seese, a father of 13, up to five times before turning the weapon on himself.
Though our hospital is created to be a place of healing, we conduct regular drills to prepare for events such as today's unfortunate situation. At this time, patient care continues in our hospital.
The hospital and nearby schools went into lockdowns for a period before being lifted later Monday.
"The safety of our students and staff is always our number one priority".
"They both had the same love interest, or dated the same girl", Detective Jason Gohlike of the Massillon Police Department told the Massillon Independent. The Massillon City School District took immediate action and placed each building in lock down for precautionary measures. "Again, the safety of our students and staff is our number one priority".
