The 29-year-old was found fatally stabbed in her Raleigh townhome early Friday morning, according to police.
Her husband, Matthew Phelps, is facing murder charges.
The couple had been married since November 2016.
According to a 911 call, Phelps said he thought he killed his wife in a dream and woke up to find himself covered in blood and her dead on the floor.
Phelps told the dispatcher he took Coricidin cough medicine because he has problems sleeping.
The makers of Coricidin later extended their “deepest sympathies” to the family and told ABC News that “patient safety is our top priority. There is no evidence to suggest that Coricidin is associated with violent behavior.”
Police said that while a full investigation is underway, they believe the crime was not a random act.
Phelps is being held without bond and is due in court Tuesday.
Meanwhile, Lauren Phelps will be honored with a memorial service at 11 a.m. at Hope Lutheran Church in Wake Forest.
