An early morning stabbing at a $2-million Highland Park home located just down the street from SMU's campus has left one person dead and another injured in what is the first homicide case that has happened in the Town since 2001.

Around 4:30 a.m., police responded to a disconnected phone call from a residence in the 3200 block of Cornell Avenue to find that two residents, John Rodman Steele and his wife Dina Steele, had been stabbed, so they were transported to the Baylor University Medical Center, according to a Dallas Morning News report. John, 50, suffered a chest injury and was pronounced dead, and Dina is being treated for hand injuries that are not life-threatening.

There were only four people in the house when the situation occurred — John, Dina and their two children who are 12 and 16 years old. No arrests have been made as of now.

The family was reportedly active in the neighborhood and involved with Highland Park United Methodist Church.
