A pediatrician was fatally stabbed at her apartment complex in Conroe, Texas, on Saturday afternoon in an attack her community is calling senseless.

Dr. Talat Khan, 52, was sitting outside the complexs common area, talking on the phone with her dog nearby, when police say 24-year-old Miles Joseph Fridrich stabbed her to death, local news outlet KHOU reported .

According to KTRK , multiple people, including children and neighbors, witnessed the killing.

Matthew Amador, one of Khans neighbors, told the outlet that he grabbed his sword when he processed what was happening and ran after the attacker.

I said, Hey, what are you doing? And just kind of spooked him. [It] didnt look like he was there, Amador told the station, noting that there was an evil look in his eyes.

When I got there, he was checking her pulse to make sure she was alive and then stabbed her three more times, Amador added.

According to police, the person who killed Khan fled on foot. Authorities later identified Fridrich as the suspect based on witness descriptions. He was taken into custody on suspicion of first-degree murder and is being held on $500,000 bond, according to Montgomery County jail records .
