“At 1:56 a.m., a neighbor’s surveillance camera showed Ms. Mogen and Ms. Goncalves returning to the house, Ms. Goncalves’ older sister said.”

“Investigators suggested that those two had slept through the killings. The house has six bedrooms, with two on each floor. The police said the victims were found on the second and third floors.
When the two surviving housemates woke up, they called some of their friends to the house, because they believed that one of the women who lived upstairs “had passed out and was not waking up.” After the friends arrived, someone from the group called 911 just before noon, and the police arrived to find the four stabbing victims.”
