CLARKSVILLE, Ohio — A catastrophic early-morning house fire in Clarksville has left six people dead, including a mother and her five young children, in a tragedy that has shaken the small community approximately 45 miles north of Cincinnati.

Authorities say the cause of the blaze remains under investigation by the Ohio State Fire Marshal’s Office.

Emergency crews were dispatched to the two-story residence at approximately 6:40 a.m. following a 911 call reporting heavy smoke and flames. By the time firefighters arrived, the structure was already fully engulfed, with flames rapidly intensifying and spreading throughout the home.

Multiple fire departments responded to the scene, working aggressively to contain the blaze and prevent it from spreading to nearby properties.

Justin Ballard, who was driving along Main Street at the time, witnessed the fire and recorded video footage showing thick black smoke billowing into the sky as flames consumed the house.

“I noticed the black smoke and pulled down there quickly,” Ballard said. “The house was already engulfed in flames. I pulled off to the side of the road, put the truck in park, and got out. There were a couple of younger men trying to spray the side of the house with a garden hose, but unfortunately it was past the point where anyone could safely enter.”

Firefighters were able to rescue one adult male from the first floor of the home.

He was later identified as Tommy Allen Jr., the fiancé of Brooke Gordon and father of the five children.

Allen sustained serious injuries and was transported for advanced medical treatment at Miami Valley Hospital.

His current condition has not been publicly updated, but officials described his injuries as significant.

Tragically, six victims were found inside an upstairs bedroom. According to fire officials, a collapsed or partially collapsed stairwell prevented crews from safely reaching the second floor in time to attempt rescue.

Initially, firefighters observed five victims on the upper level. However, during a more thorough search later in the day, authorities confirmed the presence of a sixth child at approximately 1:30 p.m.

The victims have been identified by loved ones as Brooke Gordon and her five children: Zayden, 10; Hudson, 8; Ashton, 6; Bostyn, 2; and Tomlyn, 9 months.

The Clinton County Coroner’s Office is expected to formally release the names in the coming days.

Three of the children were students in the Clinton-Massie Local School District. In a message sent to families, the district superintendent confirmed the deaths of a mother, three students, and two other children connected to the school community.

“This is devastating news for our school community,” the district said in a statement. “Our thoughts and deepest sympathies are with the family’s loved ones and all who are impacted.”

The district also announced it is working with a local crisis response team to provide emotional support services for students and staff.

Additional counselors and mental health professionals will be available beginning Wednesday. “We encourage any student, staff member, or family who needs support to reach out,” the statement added.

Eight firefighters were treated at the scene for smoke inhalation but are expected to recover.

As investigators continue to examine the origin and cause of the fire, members of the community have begun rallying around the surviving family member. A GoFundMe campaign has been established to assist with funeral expenses for Brooke and the children, as well as to help Tommy Allen Jr. with medical costs, housing, and essential needs as he begins the long process of recovery and rebuilding.

Community members describe the loss as unimaginable, with grief reverberating throughout Clarksville and surrounding areas. Friends and supporters say the outpouring of donations, prayers, and shared memories reflects the profound impact the family had on those around them.

Officials have not yet indicated when additional details regarding the investigation will be released.
