INDIANAPOLIS -- A suspect in Thursday night's slayings of seven members of a family surrendered to authorities Saturday evening, police said.

Desmond Turner, 28, of Indianapolis -- suspected in the fatal shootings of three boys and four adults in an east-side Indianapolis house -- surrendered to two officers at a fast-food restaurant near downtown shortly after 7 p.m., police said.

The surrender was arranged by someone who called an officer at the local arrestee processing center, police said. Turner, accompanied by relatives and possibly a minister, went to the restaurant as arranged, and police took him into custody there, police said.

"It's my judgment that Mr. Turner had no place to go," Indianapolis Deputy Police Chief Tim Foley said at a press conference. "He didn't turn himself in out of remorse. He turned himself in because he had nowhere to go."

Turner is being held on seven counts of murder and seven counts of felony murder -- charges that could make him eligible for the death penalty if convicted, police said.

SWAT team searches of two east-side Indianapolis homes on Friday evening and Saturday morning had failed to yield Turner.

Authorities said they arrested another man suspected of being involved in the shootings -- James Stewart, 30 -- on Friday afternoon. Stewart also is being held on murder charges.

Foley said Saturday that police believe Turner and Stewart were the only ones involved in Thursday night's shootings. If anyone else is arrested in the case, it could be on charges of assisting a criminal, Foley said. Investigators had said information from at least one witness led them to believe Turner was involved.

Among the dead were Alberto Covarrubias, 56; his wife, Emma Valdez, 46; and their sons Alberto Covarrubias, 11, and David Covarrubias, who was 8 or 9.

Also killed were Valdez's two adult children, Flora Albarran, 22, and Magno Albarran, 29; and Flora Albarran's son, Luis Albarran, 5.

Police said that through Stewart's arrest on Friday, investigators found what they believe could be substantial forensic evidence in the slayings case. Authorities said tips led them to suspect Stewart in the case.

Police Found Seven Dead In Home

Police learned of Thursday night's shootings through 911 calls at about 10:15 p.m. Thursday. Everyone in the house was dead when officers arrived, and the bodies of the three boys were found in one bed, police said.

Witnesses told police they watched Flora Albarran -- who apparently had come to the home to pick up her son -- walk in the house. A friend of Albarran's, who was in a car outside, and other witnesses told police they heard gunfire and Albarran screaming.

Police said they believe robbery was the motive and that Turner was involved. Authorities have not said what, if anything, was taken from the home.

Witnesses said they saw two to four black males emerge from the house after the shootings, but on Friday, police said they believe only Turner and Stewart were directly involved.

Suspect Is On Probation

Police said Turner has a criminal record. He was sentenced in 2002 to six years in prison -- two of which he served -- for a violent crime involving a weapon. He still is on probation for that conviction.

While in prison, Turner took part in a program in which he encouraged parents to talk to their children about gun violence, 6News reported.
