Dr. Todd Graham was killed after an opioid disagreement with the husband of one of his patients, according to St. Joseph County Prosecutor Ken Cotter.

From Wednesday, July 26, 2017:

In a statement released on Wednesday evening, South Bend Orthopaedics, located in the same medical complex as the Saint Joseph Rehabilitation Institute where a doctor was shot and killed on Wednesday, indicated that they will close two of their offices on Thursday.

The statement read:

Due to the circumstance of the traumatic incident that happened to our dear friend and colleague Todd Graham, MD, the SBO offices located at 53880 Carmichael Dr. and 60160 Bodnar Blvd. will be closed on Thursday, July 27, so that our employees can begin to cope with the loss of our beloved physician. Staff will be offered counseling services at both office locations starting at 2:00 pm on Thursday, July 27. Please join us in keeping Dr. Graham and his family in your thoughts and prayers.

Just before 1 p.m., Dr. Todd Graham was targeted by the suspect in an isolated attack, according to Commander Tim Corbett of Saint Joseph County Metro Homicide.

Police say the suspect is dead, and they believe he took his own life outside a friend's home near Dragoon Trail in Mishawaka. He has not been identified.

Police say the victim and suspect had a confrontation earlier in the day, but their exact relationship wasn't revealed.

"There's been other information that's been obtained that perhaps this has been a building situation within the suspect," said Commander Corbett.

Police had described the suspect as a white man in his 40s or early 50s who was driving a faded red Dodge Neon.

That vehicle was found at a home near the intersection of Dragoon and Valley trails - a home police say is owned by a friend of the suspect's.

"[The suspect] went to a friend's house," said Corbett. "He called the friend to let the friend know that he was leaving certain items... We did find [the suspect's] body about thirty yards from the front door of his friend's home…outside in the yard."

Corbett commended the responses of all agencies involved, saying no one could have prevented the incident.

"If you’re a target of someone, if that’s the way this ends up being, if it wasn't today it's going to be tomorrow," Corbett said. "People 'what if' a lot of things, but I wouldn't want to put that off on somebody else. That’s not fair to put on anybody."

South Bend Orthopaedics was one such agency praised by Corbett.

"There were patients in there, so you had nurses who were protecting the patients by sitting with them and doing what they thought they needed to do," Corbett said. "I have to give South Bend Orthopaedics a lot of credit. They were right on top of it, they did exactly what they were trained to do, what they were told to do, and they acted that out properly."

In addition to his work with Saint Joseph Rehabilitation Institute, Dr. Graham also served as a consulting physician for the University of Notre Dame. The University released a statement on Wednesday acknowledging Dr. Graham's work and extending their condolences.

"The University of Notre Dame joins with the community in mourning the death of Dr. Todd Graham, who served as a consulting physician in our athletics department. Our condolences go out to his family and friends, and our prayers are with them."

Saint Joseph Health System placed all facilities on temporary lockdown. At around 5:30 p.m., the lockdown was lifted.

A patient who was at South Bend Orthopaedics near S.R. 23 that closed was at the building when it went on lockdown around two o' clock.

"All of a sudden they locked everybody down on the east side of the building, and everybody was asking what was going on and they said 'someone had just got shot,'" said Patient James Wardell. "We stayed in lockdown for about 20 minutes and they said 'everybody can go, leave the building and go to the car.'"

Dr. Graham was well known in the medical community throughout Saint Joseph County. Coroner Mike McGann was a good friend, who also was called to the scene.

McGann was devastated to hear the news, but said he has a duty to fulfill.

"I still have to do my job," McGann said. "This is the fifth call we've been on today and it's not going to be the last. You have to be able to compartmentalize what we do and move on to the next call and not be disrespectful about it."

A prayer service will be held at noon on Thursday at the chapel in the Mishawaka Medical Center.
