A man at the complex, who identified himself as being the father of one of the victims, told CBS 11 News reporter Steve Pickett that his daughter and her co-worker were both shot. He said the two were employees at Cross Creek.

Late Thursday morning investigators were at the scene focusing the inside of the apartment leasing office and a black pickup and white SUV outside in the parking lot.

The suspect fled from the scene and is still on the loose. While authorities said they believe the shooting was an isolated incident, students at area schools have been advised to be aware of their surroundings when leaving campus as the search continues.

Hours after the deadly shooting Plano police did make an arrest at the apartment complex, but said it was “unrelated” to the shooting of the four people earlier in the day.
