The robbers went to the house on Bee Tree Lane seeking money and drugs, police say.

On entering the front door, they immediately began assaulting Ricardo Casteneda Jr., 24, investigators believe, before one of the robbers fired numerous rounds at Casteneda, striking him several times.

Casteneda tried to flee but was run down by the robbers and shot again and again, left bleeding on the floor and presumably dead, police say.

The men then turned their attention to Casteneda’s 17-year-old girlfriend, Nancy Mata, homicide Sgt. Joe Loughman said.

“The suspects questioned Mata as to the location of both drugs and money,” Loughman said. “Although Mata provided the requested information, the suspects killed her execution-style.”

On Thursday, police arrested a second suspect in the case. Aaron Rios, 19, was armed with a handgun when he was arrested by south patrol and fugitive officers, Loughman said.

Daquarias Dennis, 18, was arrested last week and remained in the Mansfield Jail on Thursday with bail set at $1 million.

Loughman said two other suspects are being sought on capital murder warrants.

“The suspects were identified after numerous hours of investigation by the lead detectives [Matt] Barron and [Tom] O’Brien as well as countless hours of research, surveillance and investigating on the part of the other members of the Homicide Unit,” Loughman said.

Loughman said after shooting Mata, the robbers stole drugs, money, jewelry, electronics and other property from the home before fleeing in a vehicle.

Casteneda ran for help from neighbors after the men fled, police have said.

Mata, a former Paschal High School student, was pronounced dead at the scene from a gunshot in the face.

Casteneda remained hospitalized Thursday.

At the time of the slaying, Dennis was on the fourth day of a 10-year deferred adjudication probation sentence for aggravated robbery and burglary of a habitation.

Prosecutors filed petitions to revoke the probation Tuesday, court records show, alleging that Dennis violated his probation by knowingly possessing a gun on Jan. 12.

Rios has no convictions in Tarrant County, court records show.

“Based on our interview with one of the suspects, it does appear that the suspects are gang members,” Loughman said.
