Authorities and witnesses say the officer, who was wearing plain clothes, was shot multiple times.
A witness at the scene who heard the gunshots told ABC13 he saw the officer running toward the motel searching for help.
"He was just bleeding everywhere, all over, and just not running right. He entered the office at the motel and he collapsed right in there," the witness said.

No arrests have been made but Houston Police Chief Art Acevedo said they have leads of the suspects involved. Acevedo said police were searching for a four-door Mercedes Benz, but that was recovered Monday night and taken to an HPD impound lot to be processed. At last check, authorities are still searching for a black pickup.
One of the suspects is described as a heavily tattooed Hispanic male in his mid-20s.
"We are going to catch you," Acevedo said. "Do yourself a favor and turn yourself in. The best thing you can do if you know this person, is turn themselves in."
Acevedo added that Rios was headed to the airport for his 2 p.m. shift when he was involved in the shootout. Rios leaves behind four kids.
This is the fifth murder to have taken place in the city of Houston on Monday. It is also the second Houston police officer killed in three weeks, and the fourth Houston police officer killed in 12 months.
