A 22-year-old man has been arrested and faces a first degree murder charge in the death of Elmira woman Erin Howlett, whose body was found in the Grand River in Kitchener in July.

The man was arrested Wednesday in Kitchener and is due to appear in court Thursday.

He faces one first degree murder charge, and further charges are pending, police said in a release. They did not offer any further details.

His name will not be released until charges are filed.

"Based on the information we have at this point we don't anticipate making any further arrests," said Waterloo Regional Police spokesman Olaf Heinzel.

"At this point, we believe that the accused person is solely responsible for the death of Erin Howlett."

The grisly discovery of the body of Howlett, 28, on July 5 by a group of teenagers swimming in the Grand River in Kitchener's south end sent shock waves through her hometown of Elmira, including the popular eatery Sip & Bite, where she worked as a waitress. 

Concern grew for Howlett this June, when she apparently vanished. According to a Facebook post by local radio station 91.5 The Beat, she was last heard from on June 27, when she departed for Toronto with an "unknown friend."

She was expected to arrive home by June 29, according to the post.

The investigation is still ongoing, said Heinzel.

"There are still some charges pending in this case," he said. "The investigation is still very much continuing so ... we are still accepting and welcoming any additional information the public is willing to share or has for us."
