A 21-year-old Cincinnati man allegedly shot to death his two teenage sisters and seriously wounded their 17-year-old friend by firing his gun into a minivan Wednesday morning, police confirm to PEOPLE.

Matthew Hayden, 21, faces two murder counts and another for attempted murder following the 2:30 a.m. incident, affidavits obtained by PEOPLE state.

Both of Hayden’s sisters – Sarah, 16, and Elizabeth, 17 – and friend Joshua Hacker, were struck “multiple times” during the shooting, James Love, a spokesperson for the Colerain Township, Ohio, police.

The van containing the three victims was parked behind Hayden’s parents’ house, and the incident occurred as his mother and father slept inside, Love says.

Love says that Hayden’s sisters were pronounced dead at the scene, and that 15 rounds were fired into the vehicle. According to the affidavits, Hacker was transported to an area hospital with 10 bullet wounds.

“The gun only held 6 rounds, so it stands to reason he had to have reloaded,” Love says, adding that detectives interviewed Hacker late Wednesday.

Love says investigators also interviewed Hayden and his father in an effort to determine a possible motive for the alleged attack.

“Drugs were not involved and neither was money,” Love says. “It was a domestic incident stemming from an internal family situation, and detectives told me earlier it’s too complicated to explain the dynamics within this family.”

Hayden’s defense lawyer, Ralph Mundy, did not return calls Thursday seeking comment.

Hayden is being held on $6 million bond, according to court officials. He was arraigned Thursday but did not enter a plea to the charges against him. Prosecutors will present their evidence to a grand jury on Nov. 2.
