Motion Alert
The motion alert showed a woman standing motionless in my backyard at 2:11 a.m.
Face ID
My phone unlocked with Face ID while I was asleep alone in the apartment.
Closet

911
The dispatcher calmly told me the intruder had already left my house.
Under the Stairs
The police found no sign of forced entry after I reported footsteps inside the house.
