A child abuse suspect killed himself during a standoff with authorities trying to arrest him Tuesday night at a northeast Dallas apartment.

Two warrant officers were attempting to serve a felony warrant about 9 p.m. when Daryl Elliott, 56, barricaded himself inside an apartment in the 7500 block of Holly Hill Drive, sheriff's office spokeswoman Melinda Urbina said.

Officers attempted to negotiate with Elliott, but he did not surrender. Hours later, they heard a gunshot inside the apartment, Urbina said.

They entered to find Elliott had died from a self-inflicted gunshot wound.

Officers didn't fire their weapons during the incident, Urbina said.

He was convicted for two charges of injury to a child or elderly person.

He faced two charges of aggravated sexual assault of a child, which were eventually dismissed.
