The Lady Techsters (3-6) were an astounding 56-percent from the field and were 10-of-16 from behind the arc.
NSU fell to 4-4 on the season with the loss.
“It’s hard when you come out and feel like you have a team that’s ready to play, and do that,” said co-head coach Brooke Stoehr. “I felt we prepared the last two days as well as we have all year long.
“We tell our kids all the time it’s about getting better, we just weren’t very good tonight,” she said. “We have to go back to the drawing board defensively. We have to have some people setup and lead.”
NSU was down 6-5 at the first official’s timeout with 15:49 to play in the first half.
Louisiana Tech came out of the break to jump out to a 21-10 run over the next 10 minutes.
NSU finished the half on a 10-4 run to end the half, and trailed 31-20 at halftime.
Walter was 10-of-17 from the field and 3-of-4 from behind the arc.
She scored 20 points in the second half alone, and had 12 in a 26-9 second half opening run by the Lady Techsters.
Three players finished in double-figure points: Walter, Whitney Frazier (15) and JaQuan Jackson (14).
The Lady Demons were led in scoring by Janelle Perez who had 11 points followed by Keisha Lee who had 10.
Kourtney Pennywell, who started for the first time in her college career, led NSU on the boards with six rebounds. Armstead followed her with five.
“One thing we never question about Kourtney is her energy and her effort,” said Stoehr.
NSU was only 15-of-24 (28-percent) from the field and 1-for-17 from the 3-point line.
The Lady Demons were also only 9-of-21 from the free throw line.
La. Tech outrebound the Lady Demons 40-33, and had one more turnover than the Lady Demons (14-13).
“This will be a great teaching tool for us. When you get punched in the mouth, you have to step and respond,” said Stoehr. “We just didn’t respond very well tonight.
“It’s one game, and hopefully we can use it as a motivator,” said Stoehr.
The Lady Demons will return to the floor on Tuesday when they take on Arkansas-Monticello in Prather Coliseum.
It will be the last time in the calendar year that NSU will be at home. Tipoff is scheduled for 7 p.m.
