Yes, the boyfriend was pointed out specifically as a POI. His name wasn't mentioned here, but I believe this was the only time one was explicitly called a POI:
"We continue to speak with him. He's cooperative," Parker said, referring to Spierer's boyfriend, adding "certainly" when he was asked if the boyfriend is a person of interest.

However, names were specifically mentioned here in this Police timeline:
-- 1:46 a.m.: She entered Kilroy's Sports Bar, leaving at 2:27 a.m.
-- About 2:30 a.m.: She entered her apartment and left at 2:42 a.m.
-- 2:48 a.m.: She was seen walking up an alley, toward Rossman and Rosenbaum's building. That time is revised from earlier police statements.
-- 4:14 a.m.: The truck was first spotted and again at 4:24 a.m. though police said they don't know if it's connected to Spierer's disappearance.
-- About 4:30 a.m.: Rosenbaum told police he saw Spierer rounding a corner toward home.
