Two people went to work at a west Houston apartment office. They never went home.

A maintenance worker found them. So did a resident who came in to pay rent. Both bodies were inside the management office at the Park at Woodlake apartments. That is in west Houston, near Westheimer and South Gessner. Houston police got the call around 6:45 p.m. on Sept. 3. Fire department medics pronounced both dead at the scene.

Their names came out later. Rosa Linda Ybarra was 67. Felix Antonio Jimenez Macz was 47. Both worked in that office. ABC13 reported both were workers at the complex.

Now a man who lived at that same complex sits in the Harris County Jail. His name is Derrick Duane Jackson. He is charged with capital murder.

Police never called it a murder-suicide. On the first night, HPD said at least one suspect was still out there. Detectives went to work. KPRC reported that they watched security video and talked to witnesses. FOX 26 reported that more police work turned up Jackson as a possible suspect.

Officers arrested Jackson on Friday, Sept. 4, at 4:50 p.m. ABC13 reported the time. FOX 26 said patrol officers picked him up. Jackson gave a statement to homicide detectives. Then he was booked into the Harris County Jail.

Court papers say what he is accused of doing. They say he shot Ybarra. They say he shot and stabbed Jimenez Macz. Both deaths came in the same act, the papers say. The papers list no motive. Police have not said why.

ABC13 reported that Jackson rented at the complex. So far that is the only tie to the office anyone has reported. Nobody has said there was a fight over rent. Nobody has said he was being kicked out. Police have not made that claim. El Tejano is not making it either.

Here is what the charge means. In Texas, most killings are charged as murder. That can mean 5 to 99 years or life in prison. But state law lists a short set of killings that go higher. One of them is killing more than one person in the same act. That is capital murder.

Capital murder is the top charge in Texas. It leaves only two punishments if a jury says guilty. One is the death penalty. The other is life in prison with no parole. There is no third choice. There is no 20-year deal. That is why two deaths in one room changes everything about this case.

Prosecutors still pick whether to ask a jury for death. That choice comes later. None of the reports on this arrest say what they will do.

Jackson does not have a bond yet. FOX 26 checked Harris County court records. It reported that prosecutors asked the judge to set bond at $1 million. The case is in the 228th State District Court. His first court date was set for Sept. 8.

The outlets do not agree on one small thing. KPRC and ABC13 list his age as 48. FOX 26 lists it as 53. El Tejano is going with 48 because two outlets report it.

There is a South Texas angle here that is easy to miss. Leasing offices sit at the front of almost every complex in the Valley. The doors stay open all day. Rent gets paid in person. The people behind those desks take walk-ins from strangers and neighbors alike. A lot of them are moms, grandmas, and family men working a steady job.

That is who Ybarra and Jimenez Macz were that Thursday. One was 67. One was 47. They were at a desk on a normal afternoon.

Two questions have no answer yet. Why did this happen? And did anything come before it that anyone saw?

Police have not answered either one. The complaint lists no reason. HPD says the case is still open.

What happens next is slow. A judge sets bond or holds him with none. A grand jury has to review the case. If it votes to indict him, the case moves toward trial. Capital cases move slow. Hearings can run for months. A trial is often a year or more away.

For now, two families are grieving people who went to work and did not come back. And a man who lived a few doors down is locked up on the worst charge Texas has.

A charge is not proof. Everyone is innocent until a court says otherwise.
