Lorenzo Jenkins is charged with three counts of criminal homicide.
Patrick Sullivan, his wife Deborah and their 26-year-old daughter Wendy were found dead October 22.
Metro police Det. Charles Taylor testified in court Wednesday.
NASHVILLE, Tenn. -
The case against a Hendersonville man charged with last month's brutal murder of a family in west Nashville has been bound over to a grand jury.
In a preliminary hearing Wednesday morning, a Metro police detective went into further detail about how the victims died and explained how investigators linked Lorenzo "Kelvin" Jenkins to the triple homicide.
Det. Charles Taylor said detectives were able to match a bloody palm print on a door frame at the family's Maxon Avenue home and fingerprints on the murder weapon to Jenkins.
The weapon, a knife, was found at the scene, still lodged in Patrick Sullivan's back.
Sullivan, 56, his wife Deborah, 48, and the couple's daughter, Wendy, 26, were found stabbed to death on the afternoon of October 22.
Investigators believe Wendy died first. Her body was found in the hallway at the entrance to a bathroom in the home. Deborah's body was found in a nearby bedroom.
Patrick Sullivan was found dead in a shed in the backyard.
Det. Taylor testified Wednesday all three victims had multiple stab wounds.
"All three victims had multiple, what I believe to be, stab wounds... [there were] very few in the actual torso of the body, some were actually behind the head, neck area [and] close to the spine. Some on the neck on the right and left side as well as some under the chin," he explained.
Patrick Sullivan's throat had also been slit.
"There was a large laceration going from one ear to his actual, underneath his chin," Taylor added.
Investigators have said the murders were drug related and the Sullivans were selling marijuana and prescription pills from their home.
Metro police said Jenkins has made statement to investigators but has said nothing to implicate himself in the crime. He cried in court following Wednesday's testimony. His mother was also present, as was the victims' family, who appeared visible shaken throughout testimony.
Police are still looking for two persons of interest.
On the morning of the murders, a neighbor across the street told police he saw Patrick Sullivan talking to two men.
A black male was seen behind the shed, urinating, while a white male was seen talking to Patrick in the driveway.
They have not been identified. Police are calling them persons of interest.
Jenkins, whose arrest history includes convictions for aggravated burglary, felony theft and robbery, is charged with three counts of criminal homicide.
