SAN ANTONIO -

Police are looking for a man who they said attacked a woman on the Ox Bow Park trail in the Leon Creek Park system around 10 p.m. Friday night.

It was the second attack in three weeks in the area.

According to police investigators, Lauren Bump, 24, was stabbed to death by Chrisian Bautista, 29, on New Year's Eve at O.P. Schnabel Park while she was out for a run. Bautista was arrested in connection with her death several days later.

Runners who use the trails said they are aware of the attacks, but have yet to make any changes to their running routines.

"It's kind of nerve-wracking, but I usually try to run earlier in the day when there's more people out, so if I have to scream, they'll hear me," said Kuluna Kennedy, who said she runs on the trails about three times a week.

Despite the fact that the assailant in the second attack remains on the loose, many families enjoyed the Leon Creek Greenway Park on Monday.

Police said the safest thing to do while running in the park is to run with a buddy or carry some type of protection, just in case you get attacked.

Runner Michael Hatchett runs on the trails once a week.

"It's crazy to think that there's someone out here that could hurt people like that," said Hatchett.

Police said the latest assailant was wearing a ski mask, and also has a spider tattoo on his neck.

Hatchett said he feels anyone could be a target.

"Most of the time I come out here and it's just one or two cops and it will be every once and a while, but now (that) they're patrolling more often, it does make you feel a little bit safer," said Hatchett.

"(Officers) are parked here more than before. I’ve seen them patrolling more and circling around, so that's more comforting," said Kennedy.

STW Krav Maga and Fitness will be hosting a self-defense seminar benefiting the Lauren Bump Memorial Fund. It will be held Saturday from 10 a.m. to 1 p.m. at Crossroads Annex. Check-in is scheduled for 9:15 a.m. The location is at 100 Crossroads Boulevard, Suite 107. Cost is $20 for three hours of training. This is open to women and girls, ages 12 and up.

Police presence has been stepped up in the area. But they encourage anyone walking or jogging in the area to keep these crime prevention tips in mind:
