The parents of Dayton gunman Connor Betts broke their silence in a statement Tuesday night, sending prayers to the victims and their families, but offering no clues into a possible motive for their son’s mass shooting that left nine dead.

“The Betts family is shocked and devastated by the events of Sunday morning in the Oregon District,” the family said through a prepared statement.

“They offer their most heartfelt prayers and condolences to all of the victims, their families and friends.”

The statement was delivered near the Betts’ Ohio home by Bellbrook Chief of Police Doug Doherty, who’s been the family’s de facto spokesperson since their 24-year-old son’s attack in Dayton’s nightlife district.

Without addressing a motive, the statement ended: “They ask that everyone respect the family’s privacy in order to mourn the loss of their son and daughter and to process the horror of Sunday’s events.”

Betts’ first victim was his 22-year-old sister, Megan. Masked and clad in a bulletproof vest, he used an AR-15-style rifle to unleash least 41 rounds in 30 seconds on the busy bar-lined street.

The slaughter left 27 others wounded, 14 of whom were hit by bullets. The others were either trampled while fleeing, or suffered lacerations.

Police have not released an official motive for the shooting.

But it was revealed by the FBI on Tuesday that Betts fell under the sway of “violent ideologies” and had an obsession with mayhem.

Other red flags about Betts’ history have also emerged, including him boasting of his knowledge of mass shootings to an ex-girlfriend, and holding a gun to the head of a former friend months before the attack.
