On the morning of June 3, 2014, James Serrano returned home from his night-shift job to find his wife, his daughter and his wife's sister dead in their Fort Worth home. He immediately called 9-1-1 and told the dispatcher, "They killed my family!"

Dead were his wife, Cynthia Serrano, 48, stabbed to death in the master bedroom; her sister, Kathy DeLeon, 35, shot in the head on the couch in the living room; and James' daughter, April Serrano, 21, shot in the head on the living room floor.

Family Members Shocked

Initial reports from family members said all the victims' throats had been cut, but the investigation revealed two had died from gunshot wounds and the other from stab wounds to her body.

The discovery of the slayings shocked the neighborhood and the family.

"I know there's death everywhere, but these three girls, three ladies, they didn't deserve this," Anthony DeLeon, husband of Kathy DeLeon, told reporters.

Ex-Boyfriend Posts to Social Media

Hours after the gruesome discovery, April's former boyfriend Cedric D. McGinnis Jr. posted the following message through social media: "R.I.P April Marie Serrano mane. Its always the innocent ones that get [expletive] over. Gone but never forgotten #lovetothefamily #lovetoher."

But in spite of his effort to deflect suspicion, McGinnis soon attracted the attention of investigators when the discovered he was April's former boyfriend.

Reluctant to Talk at First

According to Fort Worth homicide detective Sgt. Joe Loughman, McGinnis voluntarily came to the police station on the evening of June 3, but would not talk with detectives about the case.

Investigators then took McGinnis back to "a location," Loughman said at a news conference.

"We were about to leave and we saw some things that … we were interested in," Loughman said. "We asked Mr. McGinnis if he would come back and talk with us a second time. He agreed once again to come up here voluntarily."

Led Police to Evidence

The second time he went to the police station, McGinnis confessed, Loughman said.

At the news conference, Loughman told reporters that McGinnis not only admitted to the murders, but he directed detectives to where they could find evidence from the scene. No other details were given.

McGinnis was booked into the Mansfield Jail and his bail was set at $1.25 million. He was charged with capital murder.

No Indication of Domestic Violence

In the state of Texas, for McGinnis to face the death penalty if convicted, there would need to be an underlying felony associated with the crime. In this case, it would be multiple victims. However, if the multiple murders were the result of domestic violence, they might not be considered a capital crime.

At the press conference, Loughman was careful to point out that there was no evidence that the murders were the result of domestic violence.

Previous Convictions for McGinnis

"We have no indication that this is a domestic-violence-related case," Loughman said. "Family members and friends told us that McGinnis and April had dated on and off again. We did not locate any reports in our system that showed any history of domestic violence between them."

McGinnis has had a few previous brushes with the law. He has a marijuana possession conviction from 2011 and a 2013 conviction for evading arrest. He was arrested for robbery in 2011, but was not indicted for the crime by a grand jury.
