What we've learned about the Dayton shooter Connor Betts

Dayton police say it's way too soon to come to any conclusions about why Connor Betts took a modified AR-15 into Dayton's Oregon District and began shooting, but that fact doesn't stop people from doing their own analysis.

Betts had no criminal background that prevented him from legally buying guns, according to Chief Richard Biehl at a news conference on Sunday and again on Monday.

Biehl acknowledged Betts ordered an AR-15 style rifle online from a Texas supplier and picked it up at an unnamed Dayton gun dealer. After the fact, Biehl said, Betts modified the gun to make it more lethal, by adding drum ammunition attachments.

In all, Betts carried with him the potential of 250 rounds of ammunition. Police found 41 spent shell casings, acknowledging that was the lowest number he could have shot. Some of the evidence may have been lost in the crime scene when hundreds ran through and first responders entered the scene.

Betts, 24, reportedly lived in the sleepy and safe suburb of Bellbrook, OH with his parents and sister. A search warrant was executed Sunday morning at the home. Local police blocked access to the street after police left the scene, to allow the family some privacy, according to the police officer at the barricade.

Since the shooting, Betts' former classmates are making claims about his behavior in high school, including his suspension for making a list of women he wanted to rape, and scrawling a hit list on the bathroom wall at this school.

Police are very cautious about making any conclusions.

"Any suggestion at this time of motive would be irresponsible," said Biehl at a Monday morning news conference. "We do not have sufficient information to answer the question everyone wants to know. Why?"

Early Sunday morning, about 1 a.m., Betts took the AR-15 style weapon into the busy street and began firing as he headed towards Ned Peppers. He killed his younger sister, Megan, eight others and shot another 14 people before being killed as he rushed the door of Ned Peppers bar on E. Fifth St. in Dayton's Historic Oregon District.

Chief Biehl says they are investigating how his sister's death fits in with this event.

"That's a question that I've asked more than once," Biehl responded to a reporters question. "I don't think we can know that for certain. It seems to just defy believibility that he would shoot his own sister, but its also hard to believe that he didn't recognize that was his sister."

Other than the 14 who were shot, the remainder of those injured, with estimates of 27 to 32 total injured, were hurt in the aftermath.

A Linked-In profile that matches Betts described himself as offering “extensive customer service experience” and “good under pressure, fast learner, and eager to overachieve.” The profile listed his employers at Chipotle in Centerville and a gas station, though the profile has since been taken down.

It indicated he took psychology classes at Sinclair Community College.
