COLLIER COUNTY, Fla. -- Court documents released Wednesday give startling new details in a brutal Collier county murder.  The papers reveal what the suspect's parents aw when they went to check on their distraught son.  The scene, so gruesome, they called 911.

Christopher Serna's parents were the people he called at 4 a.m. on July 26, 2011, after he allegedly brutally murdered his girlfriend, Suzanne Bishop.  In the documents his parents say they beileve their son could be violent and with the amount of blood they saw inside, they thought someone else was there with their son.

July 26, 2011 is the day Christopher Serna is accused of murdering and dismembering his girlfriend, Suzanne Bishop, in a Collier county apartment.  In court documents obtained by WINK News Wednesday, a picture is painted of what Serna's parents saw, for the first time.  They tell detectives when they showed up at the apartment, Serna would not let them inside but they did call 911.

Serna's father, Lionel, told detectives "I went in a couple steps, looked around, saw blood all over the floor."  Detectives ask "Did you see any blood on Chris?"  Lionel replies, "Yeah, he was all blooded up."

Detectives asked Lionel where the blood could have come from.  He said "I saw it on the floor and he must have had someone in the apartment."  Lionel goes on to say their son didn't say if someone else was in the apartment

WINK News tried speaking with Serna's family in September.  We were told to leave or they would call police.

Serna's mother, Adelina, told detectives a similar story.  Detectives asked "You said you saw blood on his hands or what you thought were blood on his hands."  Adelina answered "Yes."  Detectives asked if she saw blood anywhere else, she answered "No, just on his face and hands."

Detectives asked Adelina if they believe her son is violent.  She said no.  They asked if he could have been driven to a violent act, she answered "Yes if someone threatened his kids."

Serna remains behind bars at the Collier County Jail with no bond.  His next court date is set for December.
