‘Very cold’ suspect arrested in connection to missing girlfriend after pair last seen out at bars fighting

Authorities investigating the disappearance of a Florida woman have taken her boyfriend into custody.

On Dec. 6, Pasco County Sheriff Office deputies arrested Collin Knapp and charged him with the second-degree homicide of Kathleen Moore, WFLA reported.

Knapp and 34-year-old Moore were last spotted together at bars in Largo and Indian Rocks Beach around 1 a.m. on Nov. 29. Pasco County Sheriff Chris Nocco said the couple were fighting and eventually headed back to Knapp’s home.

“We have no evidence that she actually left that residence,” Sheriff Nocco claimed.

Friends previously told WFLA they last spoke with Moore on Nov. 28.

A homeless man reportedly found Moore’s cell phone in a dumpster not far from Knapp’s home, and investigators “digging through the dirt” found bloody clothing at a local landfill that came from a Port Richey steakhouse dumpster where Knapp worked, Nocco said.

Blood and DNA evidence as well as Knapp’s allegedly inconsistent statements reportedly led to authorities having probable cause to arrest him for Moore's murder.

Sheriff Nocco said no body has been recovered and Knapp was uncooperative and “very cold” with detectives asking for his help. “We wish Collin would provide us the information of where Kathleen is.”

The suspect has had multiple felony arrests since 2004, including for domestic violence, according to WFLA.
