The incident comes just days after a Texas man shot and killed two intruders after they broke into his apartment on Saturday and fired shots at him.
Upon arrival, officers saw two male suspects suffering from apparent gunshot wounds. One suspect was inside the apartment, the other was outside near the same residence, police said. While paramedics responded, both suspects died at the scene.

Detectives were still unsure about the details of the shooting as of Tuesday.
"Not really sure why that happened, or why they were there, or if there is any association with one another," Garland police Officer Matt Pesta told FOX 4. "We also don’t know how the two deceased know each other at this point."
