SAN DIEGO (CBS 8) - An arrest was made in connection to a body found in a suitcase in downtown San Diego.

Palmer is being charged with one count of murder. He is due to be arraigned on Tuesday.

"He seemed like he was abusive or some kind of controlling manner relationship. Whenever I would ask about him, she [Shauna Haynes] would not really talk about him. I don't know if she was protecting him from me because I was like her big brother," said Austin Palser, childhood friend. 

The body of 21-year-old Shauna Haynes of San Diego was found stuffed into a suitcase that turned up behind a Core-Columbia inn.

"It was just heartwrenching to just figure out that it was her," said Chelsea Palser, Haynes' childhood friend.

A man staying at the Chadwick hotel in the 600 block of A Street found the travel bag near a row of trash cans at the rear of the three-story building about 11 a.m. Wednesday, according to San Diego police. Noticing what appeared to be hair protruding from a zipper on the case, the man made an emergency call, Lt. Ray Valentin said.

Evidence suggests that the "medium sized'' suitcase containing the dead woman had been dumped in one of the trash cans next to which it was found, Valentin said.

"I don't want people to remember her as the girl who was found dead in a suitcase. I want people to remember her as a fun loving girl who may have been sucked into the wrong crowd, but it happens to the best of us," said Chelsea. 

A man who wheeled the bins from the curbside to the parking lot prior to the discovery of the body told police it had felt unusually heavy, the lieutenant said.
